Fallacy alert:

That being said, I sincerely thank you for taking the time to 
substantively answer the questions I have posed to the extent that you can.

True.  That's because it is putting the cart before the horse a bit. 
Looking at the current set of errors, I see no coherent pattern.  That 
might be a failing on my part.  That might be because there is a lack of 
order.  (You seem to suggest that the policy is: scream loudly enough 
and you too can get your favorite pet peeve disallowed, that being said, 
I can point to counter examples, but let's not digress...)

Without knowing what problem these errors are trying to solve, I don't 
feel I can submit bug reports.

Interop issues might be one criteria.  Might not.  I can name other 
criterias that might or might not work.

It might help if I we looked at some real data.

I recently did an exercise where I did a quick (and I must stress: 
quick!) sort of a number of web sites and analyzed the errors produced.

I can't imagine any valid reason why one should expect to find a 
trailing semicolon in an anchor tag despite the fact that it does not 
cause any interop problems:

I can see valid reasons for one to ignore the requirement that 
ampersands must be escaped in attribute values that represent a URI:

http://intertwingly.net/stories/2010/03/21/www.sina.com.cn#escape

My sort may be bogus.  People may differ on where to draw the line.  But 
I think that these are the questions that need to be discussed before 
scores of bugs are filed.
