I suggest that even though this is doable, it is not consistent with
current practice -- and I'm not talking about technical matters here.
Much of the HTML documentation (NCSA's primer, CERN doc, etc.) says
that <P> is a paragraph separator, not a paragraph container. I think
this is the way 95% of the HTML authors see it in their heads.

I suggest HTML+ use a new name for this paragraph container element,
say PP. When folks mean paragraph separator, they can write <P>. When
they mean container, they can write <PP>.

We should introduce this element into HTML also. I think it's a
trivial change to Mosaic, lynx, etc. to introduce support for a PP
element.

It's a bad thing to have the same name mean two different things in
HTML and HTML+.

Is there a formal description of exactly what errors are handled by an
HTML+ implementation?
