Subject: Re: [xacml] WSPL - XACML gap analysis

Now for the other questions:

We have not in the past found any need for separate discussion group threads.
We have occasionally encouraged participants to put some key word into the
Subject line of their mailings on a particular topic.  So far, the mail on
this topic seems to be of interest to the entire TC, so there does not seem
to be a need.

XACML does not have IP terms defined as part of its charter.  The following
response that we made to IP complaints at the time of the OASIS standards
vote expresses our intent:

We will continue this approach in our WSPL work.

>4) are there separate calls planned for this activity?

Not at this time.  In the past, we have added Monday "focus group" calls when the
work load became heavy.  Right now, that does not seem necessary.  We do most of
our work on the mailing list.
