CD-1 issue #18: redundant functionality in multiple profile

The issue number refers to the XLS-sheet found in this email:
http://lists.oasis-open.org/archives/xacml/200909/msg00013.html

The commenter points out that some of the functionality in the multiple 
resource profile can be realized by alternative means.

Yes, this is correct, but I propose that we keep it like this to be 
compatible with 2.0.

Best regards,
Erik
