It's valid, as Philip Taylor noted.
I certainly like that better than holding session state data in <meta> tags,
which is what happens on now. I've always thought that linked data meta data
should be both displayed (not just exposed) and formally a Citation, a
reference to that which is written, (with style a separate issue).

If the 'form auto-completion' is the (correctly spelled and) qualified element
CURIE, I'm in :)
