I really don't understand that assertion.  Why should
a page description language be predicated on a single
column model and force users to use floated elements in
order to achieve multi-column layouts ?  Surely the poorly-
supported "display:inline-block" model is tacit recognition
that HTML and early CSS were deficient in this very area ?

Yes, of course I can author in XML : but if I do so,
I cannot serve the resulting documents across the
web with more than the faintest hope that anyone will
be able to render them.  (X)HTML is the /lingua franca/
of the web, but it is closed (inextensible); what I am
arguing is that the /lingua franca/ needs to be extensible,
not that one should be forced to abandon it simply in order
to gain access to a richer extensible tag set.

Exactly as was TeX : yet Knuth had the foresight to realise
that no closed finite set of tags could ever satisfy the
needs of "any intelligent person" so he deliberately made
the language extensible; the author(s)/creator(s) of HTML
seem totally unaware of this fundamental need for extensibility.
