So do I, as I hope the recent debate makes clear.

I think syntax is the wrong word for it.  As I see it, XML has one
data model (described by the infoset), RDF another and topic maps a
third.  Operating on the DOM level is not operating on the syntax
level, it is operating on the XML data model level.

Good point.  If time allows, I will have a look.  The one API I have
looked at, DATAX, did not seem to match at all, but it's worth looking
at the others as well.

At the moment there are, as far as I know, only two topic map APIs
available publicly, both of which can be found at
