Saxon

In some release Saxon 9.9 on the Java side got a convenience method http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#transform-javax.xml.transform.Source-net.sf.saxon.s9api.Destination- to use XSLT 3 with Xslt30Transformer to have both the initial context item as well as the global match selection set to the input Source and use an apply-templates based processing.

I wonder whether the .NET side Xslt30Transformer is also supposed to have such a convenience method or whether due to lack of Source on .NET this is an intended omission on .NET.
