Re: [Issue 4288 PRIMER] Updated Primer Proposal for Action 217 and Issue 4288

|hirsch: why is the following sentence in the proposal needed?

    |"Where a behavior is not engaged, the absence of policy
    expressions  does not indicate anything about the |capabilities and
    requirements of a service."

|Doesn't the previous sentence in the proposal (shown below here) make  
the point regarding the absence of a policy |assertion?

    |"When a policy assertion is absent, a policy aware client should 
    not conclude anything (other than ‘no claims’)
    |about the absence of  that policy assertion. "

 >>Monica comment: Frederick,
We are attempting to differentiate policy assertion and expression, and 
the treatment thereof (granted more work may be needed and in the 
current sections, an optimal place to do so has proved a challenge).  
This could be shortened so folks understand the differences with:

    |"The absence of policy expressions does not indicate anything about
    the capabilities and requirements of a |service."

One prime intent was to move this text up so it is understood where we 
talk about assertions and expressions (with a subtle reasoning to 
differentiate) given the preceding text in this section particularly the 
last sentence, reference:

    Like Contoso’s optional support for Optimized MIME Serialization,
    there are behaviors that may be engaged (in contrast to must be
    engaged) for a Web service interaction. A service provider will not
    fault if these behaviors are not engaged. Policy assertions can be
    marked optional to represent behaviors that may be engaged for an
    interaction. A policy assertion is marked as optional using the
    |wsp:Optional| attribute. Optional assertions represent the
    capabilities of the service provider as opposed to the requirements
    of the service provider.
