CD-1 issue #31: acknowledgments

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

The list of acknowledgments must be updated. It is my understanding that
it is the task of the chairs to collect the list of of acknowledged people.

Could you do so Bill and Hal?

Best regards,
Erik
