Agreed. Another example of an authoring-conformance requirement that's not a
document-conformance requirement is
http://dev.w3.org/html5/spec/syntax.html#the-doctype - the "The DOCTYPE legacy
string should not be used unless the document is generated from a system that
cannot output the shorter string." statement.

Granted, that's only a SHOULD-level requirement. But it nevertheless states
conformance criteria that is not checkable given a document alone; checking it
instead also requires that you have some knowledge of how the document was

Anyway, I think as far as making things more explicit, the distinction is that
document-conformance requirements can be checked by looking at a document in
isolation from however it was generated or in isolation from whoever wrote it.
