/wst:RequestSecurityToken/wst:Claims

This optional element requests a specific set of claims.  In most cases,

this element contains claims identified as required in a service's 
policy. Refer to [WS-Policy] for examples of how a service uses policy 
to specify claim requirements.  The @Dialect attribute specifies a URI 
to indicate the syntax of the claims.  No URIs are predefined; refer to 
profiles and other specifications to define these URIs.

We are unable to follow what is meant here. What language is used to 
specify claims for different token types?

There is a reference here to examples in WS-Policy (Sep 2004) but no 
other detail. WS-Policy (Sep 2004) does not specifically discuss this 
issue nor does it offer an example of a service using a policy to 
specify claim requirements.

I am also not sure what the role of "profiles" and the @Dialect 
attribute is. Is this a reference to WSS 1.x profiles or to forthcoming 
profiles to developed
as part of WS-SX?

Is the intent here to allow policies from WS-SecurityPolicy to be
expressed?

Proposed Resolution:

My guess is that this should reference is WS-SecurityPolicy with 
language like:

policy.
Policy expressions taken from WS-SecurityPolicy may be used to describe 
the claims sought by the requestor.

But this still leaves open the role of @Dialect. So I need the questions

given above to be answered first, before I can propose alternative text.
