valid entityid? urn:federation:apptio

[Nate Klingenstein]

Jim,

Microsoft uses urn:federation for a variety of things.  It's not registered with IANA AFAIK.

http://www.iana.org/assignments/urn-namespaces/urn-namespaces.xhtml

I haven't seen others trying to use names in that namespace that before.

I believe it has been communicated to Microsoft that using registered namespaces that you own is better.  Whether it's a show-stopper depends on whom you ask, I guess.  My hunch is it would be really hard for them to stop using current identifiers, and getting harder every day.

Hope this helps,
Nate.
