Re: [xslt] suppressing warning from document()

You might investigate XML::LibXML::InputCallback:

If you override that you can search for the file in your own code.  This
may not work with AxKit (which I haven't used) and it may have some
performance issues.  I implemented it once and got it working but ended
up deciding to pre-process the XSLT instead which worked better for my

It would be nice if there was a "include path" for XSLT.  Though I
suppose that would be engine-specific, not part of the specification,
and therefore not always supported.  Or maybe it's there and I'm too
ignorant to know.  ;)
