I am arguing that the specification should not attempt
to define what may, or may not, appear as the content
of any attribute the content-model of which is effectively
"plain text".  The specification may (and should)
/recommend/ the use to which the field should be
put, but it cannot (and should not) mandate it, since
it would be impossible for a validator to ascertain
whether or not a particular document was violating the
specification.

Absolutely agree.

Since we can never know (in advance) "the kinds of information that people
might put in there", I cannot agree that such a consideration should
provide any input to the design of HTML 5.

Then that is one part of the specification that I believe
requires further examination, for reasons directly analogous
to those given above.
