I was thinking that the current document could be cleaned up, 
reviewed by the WG, and released as a Working Group Note -- this 
would give it some status, make it easy for implementors to find, but 
not make it part of our recommendation - I think that would be a good 
status for it, and it would complement our document set.  it would be 
made very clear that this is an informative and incomplete document 
-- title could be something like "HInts for Implementors ...." or 
something like that
