I think my proposal has been integrated just fine from what I can see.
I have a few niggles about the XRID stuff, though:
* The "URI" element should not be mandatory inside "Service". Firstly
both the OpenID and LID capabilities define what happens in the case
where it is ommitted, and secondly not all services will have a URL
endpoint. Consider for example:
While it is admittedly unlikely that anyone would use TypeKey through
YADIS, it provides a good test case for services that are not URL-based.
Related to this is that there needs to be some more said about how the
extra per-service elements are added. The spec seems to suggest that the
service is free to dream up new XML elements and use them, which might
make some XML-heads squirm. If that was the intention though, it should
probably be made specific in the spec.
The cleaner solution would be to mandate the use of XML namespaces as I
did in my example, but that's an extra overhead for a format that's
currently quite simple and unencumbered by such things. I see that
Drummond Reed's original proposal made use of a namespace for the
"keyInfo" element, but the namespace was not declared.
* Minor nitpick: you left in some of the comments like "I think YADIS
has this" in the format spec. It's probably best that our own spec isn't
so indecisive about what it does! :)
