Attributes

Name	Type	Description
After	String	The identifier of another package that this one should be installed after. By default the After attribute is set to the previous sibling package in the Chain or PackageGroup element. If this attribute is specified ensure that a cycle is not created explicitly or implicitly.
Cache	YesNoAlwaysType	Whether to cache the package. The default is "yes".
CacheId	String	The identifier to use when caching the package.
Compressed	YesNoDefaultType	Whether the package payload should be embedded in a container or left as an external payload.
Description	String	Specifies the description to place in the bootstrapper application data manifest for the package. By default, ExePackages use the FileName field from the version information, MsiPackages use the ARPCOMMENTS property, and MspPackages use the Description patch metadata property. Other package types must use this attribute to define a description in the bootstrapper application data manifest.
DisplayInternalUI	YesNoType	Specifies whether the bundle will show the UI authored into the msp package. The default is "no" which means all information is routed to the bootstrapper application to provide a unified installation experience. If "yes" is specified the UI authored into the msp package will be displayed on top of any bootstrapper application UI.
DisplayName	String	Specifies the display name to place in the bootstrapper application data manifest for the package. By default, ExePackages use the ProductName field from the version information, MsiPackages use the ProductName property, and MspPackages use the DisplayName patch metadata property. Other package types must use this attribute to define a display name in the bootstrapper application data manifest.
DownloadUrl	String	The URL to use to download the package. The following substitutions are supported: 0 is replaced by the package Id. 1 is replaced by the payload Id. 2 is replaced by the payload file name.
Id	String	Identifier for this package, for ordering and cross-referencing. The default is the Name attribute modified to be suitable as an identifier (i.e. invalid characters are replaced with underscores).
InstallCondition	String	A condition to evaluate before installing the package. The package will only be installed if the condition evaluates to true. If the condition evaluates to false and the bundle is being installed, repaired, or modified, the package will be uninstalled.
InstallSize	String	The size this package will take on disk in bytes after it is installed. By default, the binder will calculate the install size by scanning the package (File table for MSIs, Payloads for EXEs) and use the total for the install size of the package.
LogPathVariable	String	Name of a Variable that will hold the path to the log file. An empty value will cause the variable to not be set. The default is "WixBundleLog_[PackageId]" except for MSU packages which default to no logging.
Name	String	The destination path and file name for this chain payload. Use this attribute to rename the chain entry point or extract it into a subfolder. The default value is the file name from the SourceFile attribute, if provided. At a minimum, the Name or SourceFile attribute must be specified. The use of '..' directories is not allowed.
PerMachine	YesNoDefaultType	Indicates the package must be executed elevated. The default is "no".
Permanent	YesNoType	Specifies whether the package can be uninstalled. The default is "no".
RollbackLogPathVariable	String	Name of a Variable that will hold the path to the log file used during rollback. An empty value will cause the variable to not be set. The default is "WixBundleRollbackLog_[PackageId]" except for MSU packages which default to no logging.
Slipstream	YesNoType	Specifies whether to automatically slipstream the patch for any target msi packages in the chain. The default is "no". Even when the value is "no", you can still author the SlipstreamMsp element under MsiPackage elements as desired.
SourceFile	String	Location of the package to add to the bundle. The default value is the Name attribute, if provided. At a minimum, the SourceFile or Name attribute must be specified.
SuppressSignatureVerification	YesNoType	By default, a Bundle will use the hash of a package to verify its contents. If this attribute is explicitly set to "no" and the package is signed with an Authenticode signature the Bundle will verify the contents of the package using the signature instead. Therefore, the default for this attribute could be considered to be "yes". It is unusual for "yes" to be the default of an attribute. In this case, the default was changed in WiX v3.9 after experiencing real-world issues with Windows verifying Authenticode signatures. Since the Authenticode signatures are no more secure than hashing the packages directly, the default was changed.
Vital	YesNoType	Specifies whether the package must succeed for the chain to continue. The default "yes" indicates that if the package fails then the chain will fail and rollback or stop. If "no" is specified then the chain will continue even if the package reports failure.
Any Attribute (namespace='##other' processContents='lax') Extensibility point in the WiX XML Schema. Schema extensions can register additional attributes at this point in the schema. The extension's `CompilerExtension.ParseAttribute()` method will be called with the package identifier in `contextValues["PackageId"]` .
PrereqSupportPackage	YesNoType	When set to "yes", the Prereq BA will plan the package to be installed if its InstallCondition is "true" or empty. (http://schemas.microsoft.com/wix/BalExtension)
