Action Item http://www.w3.org/2006/07/12-ws-policy-minutes.html#action01

Folks, 

Per our action item on [1], here is our outline for the Guidelines for
WS-Policy Assertion Authors document. 

We realize that there is some overlap with the submitted Understanding
WS Policy document [2] content. Our intention is however to focus on
guidelines for policy authors rather than detailed descriptions of the
policy framework itself. We feel that the content should be tailored to
guiding authors in making the best choices. You will find the outline
illustrates this intent. 

We will prepare a detailed proposal as to which sections of the UWSP
document may also be used within the context of our guideline as the
next step.  

Cheers,
