I agree with Andrew on this suggestion. I don't think the UI WG
proceeded differently for any particular reason, except that no such
convention existed and we were not aware of side-effects previously.
Regardless of interoperability issues with existing libraries, I
thinking having a type URI for the extension is desirable from purely
semantic standpoint (if a human were to read such document, it would
be more logically organized with 'umbrella' type URIs for the extension).

Hi folks,
Breno just pointed out to me that the UI extension's draft spec,
Discovery section
<http://wiki.openid.net/f/openid_ui_extension_draft01.html#anchor6> calls
out two type URIs that should appear in an OpenID identifier's
XRDS document. But neither of these type URIs is the type URI of
the extension itself.
DotNetOpenId and DotNetOpenAuth both take for granted that an
extension's primary type URI (the one that appears at the value of
the openid.ns./someext/ parameter) is expected to appear in an
XRDS document if the OP supports that extension. Maybe that
wasn't a spec'd out behavior for OpenID extensions, but it seems
to hold true for the OPs I tested at the time.
While it's neat to see the UI extension include a specific
Discovery section that allows OPs to declare their support for the
different parts of the extension, there's no mention of declaring
the extension itself. As a result, RPs (at least the ones based
on DNOI/DNOA) may not think that an OP supports the UI extension
when in fact it does.
So I'm requesting two things:
1. Can we get the UI extension DRAFT spec updated to include
that the http://specs.openid.net/extensions/ui/1.0 URI be
included in the XRDS document?
2. Can we standardize on the idea that an extension's type URI
should be in an XRDS document if the OP supports it so that
RPs can easily scan for all supported extensions? (this
would be in addition to any additional type URIs the
extension wants to define and advertise)
What do you all think?
