Hi Joseph,

you're right about that ID stuff. A nice reading on that is [1]. What I see 
from the feedback from users of the Apache XML Signature implementation is 
that a general ID-type attribute which can be applied even without 
DTD/Schema is really a problem for many users. IDs which refer e.g. to 
<ds:Object> often work in different implementations because a ds:*/@Id is 
(by implicit knowledge) of type ID.

If the W3C could make a proposal on how we can use IDs WITHOUT DTD/Schema, 
that would be a GREAT deal.
