   URIs as IDs in ModSAX (was Re: ModSAX (SAX 1.1) Proposal) (fwd)

This and previous forwarded from an (accidentally!) off-list discussion.

To recap, the proposal is that SAX feature identifiers are typed as URI
(ie. superset of URLs and URNs) to give a globally managed namespace,
without associating additional semantics with those names.

Yes, using URIs was my original idea, and I'm still very partial to
it; I've been using the Java-package-style names in my examples, but
I'd like to know what everyone thinks about the issue.

I'd prefer not the use the java.net.URL class, though -- I don't think 
it buys us anything, since the URIs are not mean to be dereferenced.

I'm strongly inclined to agree.  Does anyone have a strong case

All the best,
