[whatwg] Syntax highlighting language attribute for editable elements

Has thought been given to allow textarea, input and/or contenteditable
elements to use an attribute (maybe like <code/> does with
class=language-XX) so that user agents might be able to display the
editable text with syntax highlighting code automatically?
This should not adversely affect users who do not have such browser
support, nor does it put pressure on browsers to implement immediately
(add-ons might take care of such a role). But having a convention in
place (even if languages are not predefined) would ensure that the
burden of implementing such support could be shifted away from the
developer if they are not so inclined.
I'd prefer to see a dedicated attribute (also on <code/>) since the
language type does convey general interest semantic information, but I
think it would also ideally be consistent (i.e., the same attribute to
be used in <code/> as in <textarea/>, etc.).
Maybe @lang/@xml:lang could be used for this purpose if its definition
could someone be widened to recognize computer languages.
It would be nice, however, to also have some means of indicating that
the web author is providing their own styling of the element in the
event they wish to use their own editor.
