It's intended, because the idea is to let UAs have just one 
implementation. Note that "xml:lang" is a namespaced attribute, you can't 
specify it in HTML without using scripting. (<html xml:lang=""> doesn't 
create a node with a namespaced attribute.)

Correct. The xml:id spec doesn't have a DOM binding. That is unrelated to 
HTML5.
