[Description] Optional ITaskItem[] parameter. Contains a list of XML files that specify the assemblies that are expected to be in the target subset. As an option, items in this list can specify the "FrameworkDirectory" metadata to associate an InstalledAssemblySubsetTable with a particular framework directory. If there is only one TargetFrameworkDirectories element, then any items in this list that lack the "FrameworkDirectory" metadata are treated as though they are set to the unique value that is passed to TargetFrameworkDirectories. [Parameter] 
InstalledAssemblySubsetTables
