Let me see if I understand correctly: 

1. Two applications directly exchanging SAML documents is not legal? 

2. The only legal interaction patterns are those described in the
profiles specification?

3. The semantics of SAML when used in interaction patterns not
described in the profiles specification is undefined?

Is that what is being stated?  /Roger
