No, disagree completely. Much of the value of declarative markup is that
processing is _not_ specified. A document means what it means and lasts
for ever. The processing model used by today's generation of
applications is just a temporary artifact of the technology and
interfaces being used to present the document. It needs to be specified
somewhere but it is separate from the specifcation of the markup. (Which
is one reason why many people are concened about the style of definition
of html5 which places DOM interaction as a primary part of the language
definition.)
