Right, ``a'' elements can't be nested in a legal XHTML, but a validator
cannot enforce this.  In HTML 4.0 or ISO-HTML, a validator does enforce
this condition.  SGML is more expressive than XML, so (in this respect)
HTML 4.0 is better than XHTML.

That's interesting.

I'm thinking I should start my adding

<LINK rev=signs href="...sig"> and then adding a webpage of a profile
describing the semantics the the "signs" relation in my profile
attribute.

Then I can see about improving this, because it would clearly be better if
I use common semantics, rather than making my own.

Do people agree that the above is an acceptable solution, although perhaps
not the best solution?  Or is there something I don't get.
