Frederick,

Thanks for the updated version that accounted for my comments.
I am good with your changes. 

Could you please send a version that does not have the change marks?

Regards,
Prasad

now which includes all editors]

Prasad

comments in line, but I agree with your concerns and attach a  
concrete amendment to the draft.

This message contains 4 proposed amendments to the draft distributed  
to the work group
(ignorable-proposal-v3.pdf). I've attached a red-line to show in  
context the proposed amendments.

Amendment #1
Replace 2nd paragraph lines 16-24 with the following text:

"The use of the Ignorable attribute allows providers to clearly  
indicate which policy assertions indicate behaviors that don't always  
manifest on the wire and may not necessarily be of concern to a  
requestor. Using the Optional attribute would be incorrect in this  
scenario, since it would indicate that the behavior would not occur  
if the alternative without the assertion were selected. "

Amendment #2
Remove 3rd paragraph entirely (lines 26-29).

Amendment #3

Add following text to follow second paragraph (at line 25)
"It is incumbent of Providers to declare the behaviors that will be  
engaged using policies although those behaviors may not exhibit wire  
level manifestations. The Ignorable attribute allows them (policy  
providers) to do so."

Amendment #4

Since the material around proposed 2.7 is written in terms of XML, I  
propose we uniformly refer to ignorable in terms of the Ignorable  
attribute. Please see the red-line for details of this change.

Thanks Prasad for the useful review.

I agree and believe we should remove this restriction. I propose  
amendment #1 to fix this.

(Note that if there is a wire manifestation then I'm not sure I  
understand how it can be ignored)

Along with your first point, if we adjust that, then this can be  
removed.

I prefer this.

Agree, thanks for reminding me of this one.
