Re: Why are there no XSLT processors implemented in XS

On a similar subject ...

When XProc was presented at XML Prague a couple of years back, I asked
Norm Walsh and Michael Kay if XSLT wouldn't be a good candidate for
implementing XProc.

Both Norm and Michael recommended against using XSLT for an XProc
implementation.

I would have thought that XSLT would be a good building block for XML
processing of this sort.

However, from the quick chat around the subject, I took away the
impression that, for these venerable experts, the task of hooking up
different input/output sources for XProc was going to be too
challenging to do in XSLT.

(Of course, Jim Fuller did an XQuery implementation of XProc, hence
one would think that XSLT could do the job, too.)
