To expect user agents to make such distinctions seems to me to be asking
them  to make too many assumptions given that there is no one-to-one
correspondence between script and language.  For instance, there is the
example
given earlier in this thread about numbers in a mixed English-Hebrew
document.
There is no simple common sense rule that a user agent could be given.


As a result, I don't think that such an ability should be added to HTML. 
At best, perhaps doing something like the following to indicate ranges
for languages could be considered for XHTML2.

<html>
  <head>
    <charlang value="he:"U+0030-U+0039,U+0590-U+05FF;en:U+0021-U+007E" />

But I don't like it.  and the more flexible alterative of adding a charlang
attribute to everything I like even less.  Trying to shoehorn this into the
existing lang and  xml:lang attributes has the problem that existing
implementations won't understand the new values, so that is clearly
not acceptable at all.

(Note:  The intention is to indicate character ranges using the same syntax
as that used in CSS2 for character ranges in fonts, and that a character
is bound to the first language encountered, thus eliminating the need for
breaking
up the range for the English characters into two discrete ranges and
providing
a defined behavior for when such double definition occurs.)
