Yes, read the HTML 4.01 specification for example. Telling you waht to put in
an element or attribute is part of defining the semantics of the element or
attribute. The specification defines both the syntax and the semantics of the
markup language.

The proposal that I was advancing in this thread relates to both the syntax
and the semantics of the ALT attribute.

No, not at all. A marked up document that doesn't conform to the semantics of
the elements and attributes as laid down in the specification is not a
conforming document, provided that the conformance requirements are
appropriately prescribed. In the case of HTML 5, when I last read the draft
there was an explicit statement to this effect.
