suggested HoK URIs and namespace prefixes

["Tom Scavo" <trscavo@gmail.com>]

I suggest the following consistent set of URIs and namespace prefixes
for various HoK-related profiles:

SAML V2.0 Holder-of-Key Assertion Profile
xmlns:hok="urn:oasis:names:tc:SAML:2.0:profiles:holder-of-key"

SAML V2.0 Holder-of-Key Web Browser SSO Profile
xmlns:hoksso="urn:oasis:names:tc:SAML:2.0:profiles:holder-of-key:SSO:browser"

SAML V2.0 Self-AuthnRequest SSO Profile
xmlns:ssos="urn:oasis:names:tc:SAML:2.0:profiles:holder-of-key:SSO:self"

SAML V2.0 Attribute Self-Query Profile
xmlns:selfqry="urn:oasis:names:tc:SAML:2.0:profiles:holder-of-key:query:attribute:self"

The first two have already been submitted (by Tom and Nate, resp.).
The latter two have not yet been submitted.

Nate, this requires a small amount of work on your part, so let me
know if you have a problem with this.
