I tried that one on AI experts some years ago. Every place I wrote IS-A on the chart, they replaced it with HAS-A. The notion that the semantic GI IS-A Type doesn't seem to be well-accepted outside the XML community. There may be something to what Steve says and namespace disambiguation points that out simply because you need a redirection. It's just a name as far as XML is concerned. We end up having to build a lot of infrastructure to make IS-A work and that means we are narrowing the options of XML. len -----Original Message----- From: Jonathan Borden [mailto:jborden@m...] It is not a simple fact at least if we are still talking about XML. XML 1.0 says that the _type_ of an element is its name or GI. Generally the 'type attribute' has a special place in the list of 'attributes', i.e. the "isa" link. So, not (element has-a GI) rather (element isa GI). The value, to me, of the namespace URI is that the "isa" link can traverse the web, which I find useful. I have no opinion about alpha-renaming, or how you might use that to traverse the web. In any case it is not typical to equate "isa" and "has-a" links and I suspect that if you do so, you will lose processing capabilities.
