Yes. But I also realise that loading three RDDL documents instead of one
(one for the XHTML namespace, one for the RDDL namespace and one for the
XLink namespace) won't help me much to understand what this XML document is
all about.

I'm glad you write that. So now, do you agree that RDDL cannot be used to
find the schemas of XML documents that contain a mix of namespaces, despite
the fact that those schemas exist (there is a DTD for RDDL, WAP 2.0, etc.) ?
Do you agree that RDDL is good at describing *namespace* meta-data (apart
from a few problems, but let's be open-minded), but NOT at describing XML
document meta-data ? Do you understand my point, which is that instead of
focusing on RDDL which solves a little part of the meta-data problem, but
looks like a sliver bullet, we should reckon the limitations of RDDL and try
to go further ?
