org.apache.tools.ant.taskdefs.XSTLProcess enhancement

           Summary: org.apache.tools.ant.taskdefs.XSTLProcess enhancement
           Product: Ant
           Version: 1.6Alpha (nightly)
          Platform: All
        OS/Version: Other
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: keeleyd@clear.net.nz


Provide the path and file name relative to the base directory as a parameter to 
each XSL transform.  We have many applications that need this relative path 
because a derivative of it is output by the transform.  e.g. we generate java 
source and the package in the java source is derived from this relative path.

After inspecting the ant nightly code drop, I think this is a one line change.  
See the one line added in the code sample below 
>From the file org.apache.tools.ant.taskdefs.XSTLProcess ...

For examples sake, I suggested the parameter name "xml-file" which would need 
to be documented as a standard parameter available to all transforms.

I would be happy to effect this change myself if you wish, obviously I would 
need access to the CVS to do so.

I look forward to your response.

Regards
Dave Keeley
