I would personally find any of the first three options acceptable  
(with suitable adjustments for wording). However, I think it would be  
far better to have a conclusive decision on any of these options than  
to continue to leave the issue open.

After the huge volume of discussion on this issue, it seems very  
unlikely to me that we will achieve consensus. So I think the chairs  
should do one of the following soon: (a) outline a concrete process  
for building consensus; (b) hold a vote; or (c) outline another  
process for making a group decision notwithstanding the lack of  
consensus.

I think this issue being perpetually open is unhealthy for the Working  
Group. My personal preference would probably be something like Rob's  
proposal (describe what summary="" does and say it may not do a good  
job of serving its purpose). But at this point, I'd accept any outcome  
so long as we can move on.

I also have a few observations.

First, Ian has often been criticized for acting unilaterally and  
ignoring the input of some or all of the Working Group. In this case  
he is directly asking the chairs to facilitate making a clear Working  
Group decision. I think the chairs owe it to him to do so. I would  
also like to see what happens if the Working Group makes a decision  
about the content of the spec that Ian personally disagrees with.

Second, since the current joint chairmanship took office, I don't  
think we've made any decisions of the Working Group on issues where  
there was underlying disagreement. I'm starting to wonder how we are  
going to resolve contentious issues in time for our Last Call target  
date, if so far we haven't exercised the process for doing so at all,  
and are continuing to kick the can down the road on issues that are  
over a year old.

Failing to make a decision here has an impact beyond the potential  
spec text changes. It leads to mailing list disputes and fosters lack  
of collegiality. It makes the Working Group appear weak and  
ineffectual, since we can't make a decision on even low priority  
issues that engender disagreement, let alone difficult high priority  
issues.
