| Name | Type | Description | Required | 
|---|
| Feature | String | Optional attribute to explicitly set the Feature when defining the software id tag                   in a Product. By default the software id tag will always be installed by a top-level hidden feature.                   It is recommended to not set this attribute. |   | 
| InstallDirectory | String |                      A reference to an existing Directory/@Id where the software is installed. The SWID tag file will be installed in a "swidtag" folder                     under that directory as per the specification. This attribute is required on a Tag element found under a Product element.                    |   | 
| InstallPath | String |                      The path where the software is installed. The SWID tag file will be installed in a "swidtag" folder.                     This is a formatted attribute so it is possible to use Variables as the InstallPath by setting                     the value to, for example, "[ProgramFilesFolder]CompanyName\Product Name". This attribute is required                     on a Tag element found under a Bundle element.                    |   | 
| Licensed | String | This attribute has been deprecated. |   | 
| Name | String |                      Name to use in the filename for the software id tag. By default the filename                     uses the Bundle/@Name or Product/@Name. If the bundle name or product name contains                     invalid filename characters such as ":" or "?", use this attribute to provide                     a valid filename.                    |   | 
| Regid | String |                      The regid for the software manufacturer. A regid is a URI simplified for the common                     case. Namely, if the scheme is "http://", it can be removed. Additionally, the domain                     should be minimized as much as possible (for example, remove "www." prefix if unnecessary).
                      For example, the WiX toolset regid is "wixtoolset.org".                    | Yes | 
| Type | String | This attribute has been deprecated. |   | 
| Win64 | YesNoType |                      This attribute facilitates the installation of packages that install both 32-bit and 64-bit files. Set this attribute to 'no'                     to indicate the software id tag is installed to a 32-bit location (such as "ProgramFilesFolder") or 'yes' when the tag is                     installed to a 64-bit location (such as "ProgramFiles64Folder"). The default default value is based on the platform set by                     the -arch switch to candle.exe or the InstallerPlatform property in a .wixproj MSBuild project:                     For x86 and ARM, the default value is 'no'.                     For x64 and IA64, the default value is 'yes'.
                      This attribute is only allowed on a Tag element found under a Product element.                    |   |
