 no argument there if I'm the xml designer, but in this case I was of course
the xml consumer, also there is one case in which it struck as being useful
to be able to switch prefixes, that being I have an xslt that writes out an?
xslt, so an xsl with the xsl prefix writes out an xsl with the tempsl
prefix, or vice-versa. However at one point we hired a new xslt guy and,
despite his having done this for a year and a half and being a datalog, I
guess that's going for a masters in computer science, he didn't really know
that there was such a thing as namespaces or that you could write xslt with
xslt and so on and so forth(it was pretty trying) anyhow as I was fiddling
around writing my prefix-switcher I thought about how much easier it would
have been for him if he could have used it to switch the before and afters
to figure out what was going on.

I solved my rss: problem with your suggestion of course, but it still does
seem like one of the most counter-intuitive things about xml I can think of.
Funny enough I came across Joe English's complaints about namespaces on
xml-dev http://lists.xml.org/archives/xml-dev/200204/msg00170.html which
reminded me of this. The question being that since my xslt used two
different prefix's for the rss namespace, did this make the xslt a
borderline document?
