Instead of having a sub-element whose semantics are applied by its name
(NO.xxx), why not have a wrapper element that goes outside an element
that may be unsupported:
A table of ...
The PROTECT element would be defined to contain an [impliciti] <PREFERRED>
subelement and an [explicit] ALT element, with the semantic that only
one of them is rendered. My SGML is not strong enough to be sure
whether the ALT tagging needs to be explicit - the notion should be that
there is exactly one top-level element in the PREFERRED part.
I seems simpler to define one wrapper element than to require
substructure in every newly defined element...
