I can imagine this in XSLT programs, but what's the problem with
SAX/DOM? Adding namespace processing to my SAX program added a single
line of code to startElement and endElement:

   if (!uri.equals(XMLDBMSConst.URI_XMLDBMSV2))
      throw new MapException("Unrecognized namespace URI: " + uri);

Granted, I only use one namespace, but if I used multiple namespaces, I
the processing wouldn't be any worse. I figure out what element I'm
processing by looking up the local name in a hash table. If I wanted to
process elements from multiple namespaces, I'd just hash on
URI^localName (using the convention proposed by John Cowan a long time
ago). I process DOM trees (which do use multiple namespaces) in a
similar manner.

What am I missing here?
