I'm sorry, I haven't the faintest idea what this means. Could you
explain more carefully what you are trying to do?

Michael,

I'm planning on providing an interface on an xsl transformation 
engine for reusing an xml source by that engine. Here is a mockup of 
the calls a user might make:

parsedSource ps = transformEngine.getParsedSource( xmlInputStream );
...
transformEngine.transform( ps, xslInputStream1, resultOutputStream1 );
...
transformEngine.transform( ps, xslInputStream2, resultOutputStream2 );
...
transformEngine.transform( ps, xslInputStream2, resultOutputStream3 );

This is a pretty arbitrary example but what I'm trying to illustrate 
is that a user of our tranformation engine may want to do the xml 
parsing up front and then reuse that parsed source multiple times.

Thus my dilema: when the transform engine parses the orginal 
xmlInputStream, should it process any xsl commands "contained" in the 
xmlInputStream or not?

Thanks in advance for your feedback.

John
