Xalan doesn't work with non-document DOM source

           Summary: Xalan doesn't work with non-document DOM source
           Product: XalanJ2
           Version: CurrentCVS
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: org.apache.xalan.transformer
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


If you pass a DOMSource which is not a Document Element as the source document 
to a xalan transformer, nothing ever matches.

This is because in transform(), xalan has the following code:
      try
      {
        this.transformNode(dtm.getDocument());
      }

It gets the Document from the dtm, and applies the transformer to it. However, 
since I didn't pass a document in as the DOMSource, getDocument() returns an 
empty document id (I assume), so xalan thinks the source document is empty.

In the sample code below, "DOM SOURCE 1" fails to work, because it passes an 
Element to the DOMSource
