ISSUES: First draft of open issues document.

Looking for feedback.  I have erred on the side of over-inclusion in order
to avoid dropping issues through the cracks. 
 
1. Have I got the W3C boilerplate right for this doc?
2. For the sections on implicit and unmentioned requirements, we need some
more text before these are worth discussing.  
3. What have I missed?
