  <!-- FileName: javaNodeInfo01 -->
  <!-- Document: http://www.w3.org/TR/xslt -->
  <!-- DocVersion: 19991116 -->
  <!-- Section: 14 Extensions -->
  <!-- Purpose: Testing Xalan custom extension "NodeInfo", implemented in lib/NodeInfo.java. -->
 
  <!-- jkesselm May 2023: What this test seems to be demonstrating is that the
       custom TrAX property SOURCE_LOCATION, which records the data needed
       for NodeInfo to report node location, is not implemented for
       Temporary Trees filled from stylesheet literal content. One can debate
       whether we should be attempting to do so.

       I would recommend considering this a Feature Request rather than a bug,
       unless the definition of "http://xml.apache.org/xalan/features/source_location"
       says otherwise. (There is not currently a documentation page at that
       URI; we'd need to dig into Xalan docs to establish this.)

      <!-- From the documentation:
	  NOTE: Xalan does not normally record location information
	  for each node.  To obtain it, you must set the custom TrAX
	  attribute
	  "http://xml.apache.org/xalan/features/source_location" true
	  in the TransformerFactory before generating the Transformer
	  and executing the stylesheet. Storage cost per node will be
	  noticably increased in this mode.

	When unknown, returns -1.

	The BugzillaNodeInfo.java driver *does* set this property.
	However, the node in question is coming from a
	stylesheet-literal element in a Temporary Tree rather than the
	input document, and it appears we have not implemented this
	feature for this case.
