Or the HTTP header. (Which is actually used in some instances by browsers,
unlike the meta tag.)  For the information that Addison is referring to, see

You could do this, though I'd be inclined to say this was an English
document, since the intended consumer is English - not French (otherwise the
commentary would be in French).

Where you really get into multilingual declarations is when you have
parallel content in multiple languages.



(Note, also, as an finniky aside, that there are pages aimed at, say, an
Indian audience where the majority of true content is in,say, Kannada, but
the navigational wrapper is in, say, English. In such documents it is less
clear which language should be used for the <html> element.  This is an edge
case, though.)

See comment #38.

Or we could ask for a new element such as <documentlanguage> that supports
multiple language values, rather than go this indirect route.

Note (particularly the www-html folks who are copied on this email) that
those comments are still being formulated by the i18n WG, and have not yet
been formally supplied to the HTML WG for consideration.)
