            This is the top-level container element for every wxs file.  Among the possible children,
            the Bundle, Product, Module, Patch, and PatchCreation elements are analogous to the main function in a C program.
            There can only be one of these present when linking occurs.  Product compiles into an msi file,
            Module compiles into an msm file, PatchCreation compiles into a pcp file.  The Fragment element
            is an atomic unit which ultimately links into either a Product, Module, or PatchCreation.  The
            Fragment can either be completely included or excluded during linking.

              The condition that controls whether the command-line arguments specified in the
              InstallArgument, UninstallArgument, or RepairArgument attributes are appended to the
              command line passed to the ExePackage. Which attribute is used depends on the
              action being applied to the ExePackage. For example, when the ExePackage is
              being installed, the InstallArgument attribute value is appended to the command
              line when the ExePackage is executed.

            By default, a Bundle will use the hash of a package to verify its contents. If this attribute is set to "yes"
            and the package is signed with an Authenticode signature the Bundle will verify the contents of the package using the
            signature instead. Beware that there are many real world issues with Windows verifying Authenticode signatures.
            Since the Authenticode signatures are no more secure than hashing the packages directly, the default is "no".

                To minimize the size of the .msm file, it is recommended that developers remove

                The Fragment element is the building block of creating an installer database in WiX.  Once defined,
                the Fragment becomes an immutable, atomic unit which can either be completely included or excluded
                from a product.  The contents of a Fragment element can be linked into a product by utilizing one
                of the many *Ref elements.  When linking in a Fragment, it will be necessary to link in all of its
                individual units.  For instance, if a given Fragment contains two Component elements, you must link
                both under features using ComponentRef for each linked Component.  Otherwise, you will get a linker
                warning and have a floating Component that does not appear under any Feature.

        <xse:remarks>
          <html:p>You can specify any valid Windows code by by integer like 1252, or by web name like Windows-1252. See <html:a href="~/overview/codepage.html">Code Pages</html:a> for more information.</html:p>
          <html:p>The ClientPatchId attribute allows you to specify an easily referenced identity that you can use in product authoring. This identity prefixes properties added by WiX to a patch transform, such as <html:i>ClientPatchId</html:i>.PatchCode and <html:i>ClientPatchId</html:i>.AllowRemoval. If the patch code GUID is auto-generated you could not reference any properties using this auto-generated prefix.</html:p>
          <html:p>For example, if you were planning to ship a patch referred to as "QFE1" and needed to write your own registry values for Add/Remove Programs in product authoring such as the UninstallString for this patch, you could author a RegistryValue with the name UninstallString and the value <html:code><html:nobr>[SystemFolder]msiexec.exe</html:nobr> /package [ProductCode] /uninstall [QFE1.PatchCode]</html:code>. In your patch authoring you would then set ClientPatchId to "QFE1" and WiX will add the QFE1.PatchCode property to the patch transform when the patch is created. If the Id attribute specified the patch code to be generated automatically, you could not reference the <html:i>prefix</html:i>.PatchCode property as shown above.</html:p>
          <html:p>The summary information is automatically populated from attribute values of the Patch element including the code page. If you want to override some of these summary information properties or use a different code page for the summary information itself, author the PatchInformation element.</html:p>

        <xse:remarks>
          <html:p>A transform contains the differences between the target product and the upgraded product. When a transform or a patch (which contains transforms) is applied, the following properties of the installed product are validated against the properties of the target product stored in a transform.</html:p>
          <html:ul>
            <html:li>ProductCode</html:li>
            <html:li>ProductLanguage</html:li>
            <html:li>ProductVersion</html:li>
            <html:li>UpgradeCode</html:li>
          </html:ul>
          <html:p>Windows Installer simply validates that the ProductCode, ProductLanguage, and UpgradeCode of an installed product are equivalent to those propeties of the target product used to create the transform; however, the ProductVersion can be validated with a greater range of comparisons.</html:p>
          <html:p>You can compare up to the first three fields of the ProductVersion. Changes to the fourth field are not validated and are useful for small updates. You can also choose how to compare the target ProductVersion used to create the transform with the installed ProductVersion. For example, while the default value of 'Equals' is recommended, if you wanted a minor upgrade patch to apply to the target ProductVersion and all older products with the same ProductCode, you would use 'LesserOrEqual'.</html:p>

                        When the Type attribute value is 'directory' the registry value must specify the path to a directory excluding the file name.
                        When the Type attribute value is 'file' the registry value must specify the path to a file including the file name;
                        however, if there is no child FileSearch element the parent directory of the file is returned. The FileSearch element requires
                        that you author the name of the file you are searching for. If you do not know the file name
                        you must set the Type attribute to 'raw' to return the full file path including the file name.

                        If omitted, the default value is '*' which indicates that the linker should generate a stable guid.
                        Generatable guids are supported only for components with a single file as the component's keypath
                        or no files and a registry value as the keypath.
                        It's also possible to set the value to an empty string to specify an unmanaged component.
                        Unmanaged components are a security vulnerability because the component cannot be removed or repaired
                        by Windows Installer (it is essentially an unpatchable, permanent component).  Therefore, a guid should
                        always be specified for any component which contains resources that may need to be patched in the future.

                        If this attribute's value is set to 'yes', then the Directory of this Component is used
                        as the KeyPath. To set a Registry value or File as the KeyPath of a component, set the
                        KeyPath attribute to 'yes' on one of those child elements. If KeyPath is not set to 'yes' for the
                        Component or for a child Registry value or File, WiX will look at the child elements under the
                        Component in sequential order and try to automatically select one of them as a key path. Allowing
                        WiX to automatically select a key path can be dangerous because adding or removing child elements
                        under the Component can inadvertantly cause the key path to change, which can lead to
                        installation problems.

                        important to note that once a directory is assigned a Component Guid Generation Seed the value must not change until
                        (and must be changed when) the path to that directory, including itself and all parent directories, changes.

            This attribute's value may either a short or long directory name. If a short directory

            However, if this name collides with another directory or you wish to manually specify
            the short directory name, then the ShortName attribute may be specified.

            This Name attribute may also define multiple directories using the inline directory syntax.
            For example, "ProgramFilesFolder:\My Company\My Product\bin" would create a reference to a
            Directory element with Id="ProgramFilesFolder" then create directories named "My Company" then
            "My Product" then "bin" nested beneath each other. This syntax is a shortcut to defining

                                to be used or updated on execution of this custom action. This attribute is
                                typically used with the Value attribute to create a type 51 custom action that parses
                                the text in Value and places it into the specified Property.  This attribute is also used with
                                the ExeCommand attribute to create a type 50 custom action that uses the value of the
                                given property to specify the path to the executable. Type 51 custom actions are often useful to
                                pass values to a deferred custom action.

      </xs:appinfo>
      <xs:documentation>Initiates dynamic costing of standard installation actions.  Any standard or custom actions that affect costing should sequenced before the CostInitialize action.  Call the FileCost action immediately following the CostInitialize action.  Then call the CostFinalize action following the FileCost action to make all final cost calculations available to the installer through the Component table.  The CostInitialize action must be executed before the FileCost action.  The installer then determines the disk-space cost of every file in the File table, on a per-component basis, taking both volume clustering and the presence of existing files that may need to be overwritten into account.  All actions that consume or release disk space are also considered.  If an existing file is found, a file version check is performed to determine whether the new file actually needs to be installed or not.  If the existing file is of an equal or greater version number, the existing file is not overwritten and no disk-space cost is incurred.  In all cases, the installer uses the results of version number checking to set the installation state of each file.  The FileCost action initializes cost calculation with the installer.  Actual dynamic costing does not occur until the CostFinalize action is executed.  The condition for this action may be specified in the element's inner text.</xs:documentation>

      </xs:appinfo>
      <xs:documentation>Installs a copy of a component (commonly a shared DLL) into a private location for use by a specific application (typically an .exe).  This isolates the application from other copies of the component that may be installed to a shared location on the computer.  The action refers to each record of the IsolatedComponent table and associates the files of the component listed in the Component_Shared field with the component listed in the Component_Application field.  The installer installs the files of Component_Shared into the same directory as Component_Application.  The installer generates a file in this directory, zero bytes in length, having the short filename name of the key file for Component_Application (typically this is the same file name as the .exe) appended with .local.  The IsolatedComponent action does not affect the installation of Component_Application.  Uninstalling Component_Application also removes the Component_Shared files and the .local file from the directory.  The IsolateComponents action can be used only in the InstallUISequence table and the InstallExecuteSequence table.  This action must come after the CostInitialize action and before the CostFinalize action.  The condition for this action may be specified in the element's inner text.</xs:documentation>

Any standard or custom actions that affect costing should be sequenced before the CostInitialize action.  Call the FileCost action immediately following the CostInitialize action and then call the CostFinalize action to make all final cost calculations available to the installer through the Component table.  The CostFinalize action must be executed before starting any user interface sequence which allows the user to view or modify Feature table selections or directories.  The CostFinalize action queries the Condition table to determine which features are scheduled to be installed.  Costing is done for each component in the Component table.  The CostFinalize action also verifies that all the target directories are writable before allowing the installation to continue.

        <xse:remarks>
                    This element is particularly useful for two problems that may occur while merging merge modules:
                    <html:ol><html:li>
                            The first likely problem is that in order to properly merge you need to have certain
                            tables present prior to merging.  Using this element is one way to ensure those tables
                            are present prior to the merging.
                        </html:li><html:li>
                            The other common problem is that a merge module has incorrect validation information
                            about some tables.  By ensuring these tables prior to merging, you can avoid this
                            problem because the correct validation information will go into the installer database
                            before the merge module has a chance to set it incorrectly.

          <xs:documentation>
                    When set to no (the default), installing a product with the same version and upgrade code
                    (but different product code) is allowed and treated by MSI as two products. When set to yes,
                    WiX sets the msidbUpgradeAttributesVersionMaxInclusive attribute, which tells MSI to treat
                    a product with the same version as a major upgrade.

                    This is useful when two product versions differ only in the fourth version field. MSI
                    specifically ignores that field when comparing product versions, so two products that
                    differ only in the fourth version field are the same product and need this attribute set to
                    yes to be detected.

                    Note that because MSI ignores the fourth product version field, setting this attribute to
                    yes also allows downgrades when the first three product version fields are identical.
                    For example, product version 1.0.0.1 will "upgrade" 1.0.0.2998 because they're seen as the
                    same version (1.0.0). That could reintroduce serious bugs so the safest choice is to change
                    the first three version fields and omit this attribute to get the default of no.

                    This attribute cannot be "yes" when AllowDowngrades is also "yes" -- AllowDowngrades
                    already allows two products with the same version number to upgrade each other.

                                    This scheduling installs the upgrade product "on top of" the installed product then lets
                                    RemoveExistingProducts uninstall any components that don't also exist in the upgrade product.
                                    Note that this scheduling requires strict adherence to the component rules because it relies
                                    on component reference counts to be accurate during installation of the upgrade product and
                                    removal of the installed product. For more information, see

                                    not roll back the removal of the installed product, so the machine will have both versions
