Question on 4.1.1 Parsing - what it covers



Do we as the Working Group consider 4.1.1 Parsing to include ONLY the 4 specific examples identified in the Success Criteria, or, do we believe that 4.1.1 Parsing to includes those 4 examples plus other things where parsing failures might affect AT?  (I know that a doctype declaration is NOT a parsing failure).


​​​​​This 4 things listed in 4.1.1 are:

1.       elements have complete start and end tags, 

2.       elements are nested according to their specifications, 

3.       elements do not contain duplicate attributes, 

4.       and any IDs are unique, 

except where the specifications allow these features.


I have been at organizations where this is broader than those 4 items, and at places where those 4 sre strickly adhered to, and no other parsing issue are identified as failing 4.1.1.


Steve Faulkners tool and blog ( seem to support the 4 items only.
