Annotation Bug

- Fixed DOM lookup of special-case attributes: id and urgency are
  not stored in the usual manner, and must be handled differently.
- Removed the responsibility of DOM to evaluate literals, because
  they are handled more effectively in A3::tokenize.
- Fixed old code that assumed ".id" instead of "id".
- Removed unnecessary diag call from annotate.t.
