RE: Client-side XSLT. Re: Bad News on IE6 XML Support

Either I explained myself badly, or you are allowing your prejudices to
show. I am using XSLT to display and a validating parser to validate. The
fact that both are on the client means that my server is not interested
until it has a complete valid document to process.

Absolutely XSLT helps. It is not essential - we could use the DOM. But it is
the combination of XML, XSLT and some simple script that allows us easily to
change the display of the form depending on the data input without round
tripping to the server. What saves the round-trips (and so improves the
performance) is not the XSLT per se, but the fact that it is being executed
on the client.
