Isn't this something of a pseudo-tautology?  Typically people use XSLT
to create an output document.  Hence no matter what the stylesheet
does, foo.xml will become bar.xml.  (Example: I'd like to "delete" all
the nodes in the source document, by that I mean foo.xml becomes
bar.xml.)   Are you trying to describe a round-about crosswalk?  That
is transform a document from one set of schema rules to another and
then back to the original form.  This isn't always posssible, and
would be difficult to do in one stylesheet.

Did you get any useful answers when you posted it there?  Next time
might be nice to spend a little time adapting the message to the forum
instead of just copy and pasting it from one to the other.  (Pet peeve
of mine.)

Most people don't follow links in this forum.  I actually tried it for
a bit, but I only have so much time and I stopped after the third or
so page.  Also, I've never used relaxer before, but I have heard of

Huh?  Google xslt identity transform.  I imagine the archives and faq
of this list comes up frequently.  (And probably the section in the
specs called "Identity transform"). (the faq)

You really need to give more information.  I have a feeling you're
trying to automatically generate the XSLT using the relaxer program.
What problem you're having is not clear though.  Googling "generating
styelsheets relaxer" gives me quite a few examples.

If you want to create a transformation by hand though, this is the
place to do it.  We don't tend to talk much about specific
applications. We will occasionally talk about XSLT processors, but
that's about it.  In other words, imagine a list that talks about c++
that might occasionally get compilier-specific.  Now you're asking
about how to automatically generate c++ from some code-templating

I don't see you using the xslt option.  Might be an issue here.  I
looked up the home page of the project and I'm assuming you've read
through the manual about how to generate xslt pages right?

Have you tried asking questions in the mailing list suggested by what
appears to be the author (I got this by google relaxer mailing list)?
