Perhaps it would have been clearer if I had avoided the use of the word "schema" though. My point was (and is) that there is an association between the namesapce URI and a set of elements -- e.g. the HTML element set, or the Dublin Core -- with their associated rules for content and, where appropriate, behaviour. >> and also as a hook to activate specific behaviour. > No more so -- and no less so -- than the localnames. Oh. There are implementations that attatch semantics to the use of a specific prefix? E.g. using "html:A" works and "h:A" does not work? That was certainly not the intent of namespaces, I am sure, and would be very unfortunate.
