[xacml] Glossary Follow on

[Hal Lockhart <hal.lockhart@entegrity.com>]

It was not clear if the lack of attendance at the last call on the glossary
was because of the time or lack of interest.

To make further progress, we could:

1. Get a volunteer to draft a new version.
2. Hold another telecon

If #2 is chosen, we need to know exactly who is going to attend, since it is
difficult to find a time that is convenient for both west coast and far
east.
