This example doesn't seem to have an association. And our markup doesn't
seem to have baseName or occurrence. So I'm confused.

But the type is an NMTOKEN attribute, that couldn't be used to
hold "World Wide Web Consortium" and besides putting human readable
content in attributes is wrong.

Sure, that sounds nice, but if we really want topic maps, why aren't
we using XTM markup?

Do you have an assembly example that uses that?

Hmm. So we've built a bridge halfway over the chasm?
