It is documented, but not in the introductory documents - I had some
problems tracking down the details myself. It is documented at:
http://www.hal.com/users/connolly/html-spec/Elements/INPUT.html
(There is a thorough listing of forms features starting at:
http://www.hal.com/users/connolly/html-spec/Forms.html)
I don't know of any other documents using hidden fields - but I
haven't been looking for them!

Good question - it should be, but I heard that some WWW clients were
displaying hidden fields! No doubt the more it gets used, the more
clients will treat it properly.
For an example of hidden fields in use view
http://indigo.stile.le.ac.uk/~sgj/STILE/index.html
click on the Search link, then view the source of the resulting
document. (It's an experimental search engine that allows exploration
of our part of the web by finding commonly linked documents.)
