Henry Thompson et al. seem to be doing a bit more than that.  It appears
that if you dereference the namespace URI + ".xsd", you consistently get a
schema back.

For instance:

To me, that's establishing a convention about XML processing and namespace
URIs without creating a formal document describing said convention - not a
good thing.  It may just be W3C practice. I'd suggest, however, that the
'W3C' outweighs the 'just' in the previous sentence.

In addition, they've provided for unchanging URIs at date-marked versions,
but it's not entirely clear how/if those date-marked locations will be
maintained as the Schemas spec evolves.
