So what? You still have defined an error as a feature. Who cares about 
document non-conformance in a particular issue when software processing 
the documents is required to process non-conforming documents in a 
specific way and it actually does that? It's like saying that the use of 
the word black as color value is non-conforming but if it is used, 
programs must interpret it as #000.

Conformance as such is relevant only in situations where conformance is 
required by law or enforceable instructions. I don't think that's a common 
situation on Earth. Besides, if the conformance criteria are pointlessly 
strong (e.g., prohibiting something that still has well-defined and 
widely implemented meaning), people who make the laws or instructions 
could (and probably should) tune them accordingly: thou shalt conform, 
except for...

I wonder whether this discussion actually relates to the IE 7 madness of 
disallowing some of the valid entity and character references without a 
semicolon. It achieves nothing but breaks many existing pages.
