the following advice and MUST level conformance requirement in regards to the
use of the hidden attribute is incorrect, a tabbed interface is not "merely a
kind of overflow presentation " a tabbed interface has distinct semantics
(role, states and properties) and interaction behaviours on all platforms. The
ability to have content only displayed on selection is a common paradigm and
useful for reducing cognitive overload especially for users with disabilities.

"The hidden attribute must not be used to hide content that could legitimately
be shown in another presentation. For example, it is incorrect to use hidden to
hide panels in a tabbed dialog, because the tabbed interface is merely a kind
of overflow presentation — one could equally well just show all the form
controls in one big page with a scrollbar."

Recommend removing the paragraph above at it provides incorrect advice and MUST
level conformance requirements for developers.
