I'd hardly described one sentence as 'awesome'. How about
some useful pointers to XSLT, stylesheets to pretty print
XSLT, etc. That would be *much* better in my book.
Here's a good example:

(I see that Tim Bray presented a paper on RDDL at
XML Europe 2001, but can't find the full paper online?)

Hmmm. RDDL consists of exactly one new element which
has a handful of xlink attributes, not all of which are
required. How's this verbose?
Or are you claiming that XHTML is verbose?

I included an example in my tutorial that demonstrates
having several XSLT stylesheets linked from one RDDL
For XSLT, use the xlink:arcrole attribute to indicate the
namespace of the resulting document.

No. No problems with the assertion, just the wrong
RDDL associates resources with namespaces, it doesn't
have anything to say about documents with multiple
namespaces -- although you can still retrieve resources
(or read documentation ) for those namespaces if there's
an associated RDDL document.
It neither mandates single namespace documents, nor
causes any difficulties when working with multiple namespace documents.
So it is not working against the goal of the Namespace REC.

What precisely is misleading? I found the spec very simple and
elegant, I didn't notice any sleight-of-hand.

No argument there. 'Appropriate' could be defined as
"I need a stylesheet to turn vocab X into vocab Y, is
there an stylesheet in the directory with an arcrole for vocab
Y'. If there is, I can use it. Excellent, RDDL has brought me
some real benefits. If it there isn't, then RDDL hasn't cost me

No, it'll give you the schema.
This seems particularly useful in circumstances such as John
Cowan described in the original thread, where he asserts that
a document conforms to a schema, but doesn't reference it
directly. I might want to test that assertion :)

Fine. But if you want to make some machine readable resources
available, where should you put them? Why not drop a rddl:resource
element into your documentation. How hard is that?
If you're suggesting an alternate mechanism then that feels
more 'verbose' or complicated that is necessary.

And that's effectively what they get when they look
at a RDDL document.

Here I disagree, what if I want to use a different
implementation of a plug-in. If the browser were RDDL
aware it could present me with some choices.

I find this assertion to be ironic, seeing as RDDL itself
makes good use of multiple namespaces to achieve it's

Fine, but I'm responding anyway, so the archives contain
a more objective viewpoint.
