Re: [xsl] Selectively applying Identity transform to multiple inputs (Multiplexer Style Sheet)

["Farrukh S. Najmi" <farrukh@xxxxxxxxxxxxxxxxxxxxx>]

Thank you all for the terrific help and support. I have it working
nicely now. This is a really solid community.

I am using the default xalan XSLT 1.0 engine that comes with Sun's JDK 5
in my open source project <http://ebxmlrr.sourceforge.net>.
I guess its time to move to an open source XSLT 2.0 implementation that
will work with the TrAX API in JDK 5. I am assuming Saxon
is the best to fit that description (and that Micheal approves of this
choice ;-) )

As background, I am working to add a "Role Based Content Filtering"
feature to our Registry / Repository to provide element and
attribute level access control to a repository of XML documents based
upon roles and other credentials associated with the subject
attempting to retrieve an XML document.

Thanks again for all the help.
