Sorry if I was unclear initially. In the past, a large part of my 
complaints about DOM level 3 related to the inability to determine 
the type of an attribute in a straight-forward way so I was very 
excited to see that now you could. :-)

Fortunately DOM 3 does not require using the processing model implied 
by W3C XML
Schema and DTDs. If you've got another processing model, go for it. 
All you need to do is map the types you do assign to namespace URIs 
and type names. I'm not intimately familiar with RELAX NG, but I 
suspect a RELAX aware processor could easily generate a typed DOM. 
It's just that two different RELAX processors might not build 
identical DOMs when it came to type information.

The only problem would arise if RELAX wanted to assign multiple types 
to the same element or attribute when building a single DOM, or if 
its types somehow did not match the element and attribute structure 
of the XML document (though I'm not sure that's a good idea in any 
case.)
