No, this isn't true. You can define processing requirements -- indeed, 
HTML5 does define processing requirements -- without being so wishy washy 
as to rely on a "shared understanding of the meaning".

For example, there are very specific rules for how to process sections and 
headings, and how they relate to outlines. These requirements apply to a 
huge number of conformance classes -- editors, screen readers, search 
engines, validators, outliners, etc.

What obsolete features are we lacking suitable "shared understanding" for?

Which two attributes? I'm not aware of anything that's lacking suitable 
conformance criteria. Since I fixed <head profile> and <meta scheme>, I've 
not heard anyone list for any other features that need work.
