[OpenID] AE: How do you agree exchange type aliases collections? (2nd post attempt)

[Mark Cross]

(if this is a second post, gmail is running more than 6 hours behind...)

I'm probably being really thick here, but I cannot find anything in the

http://openid.net/specs/openid-attribute-exchange-1_0-05.html 
<http://openid.net/specs/openid-attribute-exchange-1_0-05.html>

Which states what the aliases will be for a profile/persona, in a way
that could described as a XRDS document what a profile is going to
consist of.

I can see that individual fields are defined as:

openid.ax.type.fav_movie=http:
//example.com/schema/favourite_movie

But say for example I want to use the schemes at :
http://www.axschema.org/types/#sreg <http://www.axschema.org/types/#sreg>

For populating my profile in my OP, if I use the Verisigin PIP, I will
have to manually create each field, clearly this is madness. Surely I
want to just log into my OP, enter the URI of a XRDS which describes
and returns a collection of fields:

<profile name=pet>
<field>openid.ax.type.fname=http://example.com/schema/fullname</field>
<field>openid.ax.type.gender=http://example.com/schema/gender</field>
<field>openid.ax.type.fav_dog=http://example.com/schema/favourite_dog</field>
</profile>

This will then create the profile "pet" which I can fill define the
values for and also clone within my OP, I may have more than one pet.

And when I go to relying sites using the "pet" schema, defined at a
URI I can automatically elect to pass over my pet(n) attribute
exchange values.

Has this been previously defined, or are there better ways to do this?
