I agree on that, but that shouldn't be too much of an issue to enforce
that restriction.

Most current languages define their syntaxes in terms of tokens, and
which tokens (or groups of tokens) are allowed on each context. Even
within the HTML5 spec, the markup's content model is defined with a
similar approach (for example, describing which elements or groups of
elements are valid as "sectioning content"). Is that ambiguous?
Honestly, I'm not too concerned on the algorythms themselves (I'm not
involved on UA making, at least currently), but mostly about how the
algorythms bloat the specification. Anyway, I don't think it'd be good
to start a side discussion within this topic.
