Such a deadlock is theoretically possible, but seems rather unlikely.

ISSUE-4 is whether or not HTML5 needs a versioning mechanism; the WHATWG 
position is no.  Those that do feel that there needs to be a versioning 
mechanism (e.g., Microsoft) seem motivated to find a solution that works 
with the HTML serialization of HTML 5.
