I agree with you.
I miss that, too.

I agree.
I doubt many authors knew it, not talking of using it, but I like it very 
much.
But that shouldn't be an argument for removing it.

I agree with you.
As I understand the XML Recommendation, the xml:lang attribute also affects 
the language of literal attribute values. Thus, xml:lang="pt" and title="The 
manual in Portuguese" is an example that violates the XML Recommendation.
Giving the already in the XML Recommendation well defined xml:lang attribute 
additional meaning also extends the meaning of an Attribute well known to XML 
authors in an unexpected way.

I "demand" (read: suggest ;-) to keep the hreflang attribute, make it part of 
the hypertext attribute collection and additionally allow it to contain 
multiple values, a language list, because the URI reference in context could 
be a URI pointing on a negotiating resource.

Bye
