I wish it were so easy to write short, clear specifications that could 
be unambiguously understood and implemented.  I wish features could be 
orthogonal.

However, bindings together with existing WebDAV features, while mostly 
orthogonal, have a few interesting, confusing or important 
interactions.

This isn't an unlimited set of work, folks.  All these issues have been 
raised before this last call period (except maybe one?) and it isn't an 
ever growing set.  We're talking about maybe half a page of new text to 
clarify important interactions to implementors, and then we're done and 
we'll have a really good spec.
