Assembly: WindowsBase (in WindowsBase.dll)
When is Internal, the TargetUri MUST be a relative reference. For a package-level relationship, the relative reference of the TargetUri is resolved relative to the pack URI of the source package that owns and contains the relationship. (Example source package pack URI: "pack://http:,,www.adatum.com,files,datapak.package/".) For a part-level relationship, the TargetUri is resolved relative to the source part that owns the relationship (TargetUri is interpreted relative to SourceUri).
When is External, the TargetUri can be either a relative reference or a fully qualified URI. If the TargetUri is a relative reference, the reference is interpreted as relative to the location of the Package that contains this relationship.
