Re: 48-Hour Call for Consensus (CfC): Make HTML 5.0 Strong Semantics Informative

Janina,

I have thought about this some more and we should say that the default
implicit semantics should be treated as informative. We need to keep the
rules defined in the spec. for strong native semantics where the author is
restricted in the on the use of roles, states, and properties on specific
elements. This can be tested with the a validator or an accessibility test
tool as these are normative authoring requirements. We don't want to wait
until a later version of HTML to start imposing those requirements. The
ARIA specification allows a host language to do this:

"Host languages MAY document features that cannot be overridden with
WAI-ARIA (these are called "strong native semantics"

I apologize for not thinking this through more earlier.

Best,
Rich

Subject:	48-Hour Call for Consensus (CfC): Make HTML 5.0 Strong
            Semantics  Informative



Colleagues:

This is a Call for Consensus (CfC) to formally request that the HTML-WG
take one of the following two courses of action with respect to
strong native semantics in HTML 5.0:

http://htmlwg.org/heartbeat/WD-html5-20140617/dom.html#sec-strong-native-semantics


1.)		 Mark this section as RFC2119 "informative" in the current 5.0
version of
HTML, with a note that it is expected to become normative in a future
version of HTML.

2.)		 Produce testing results that validate maintaning this
section's
current RFC2119 normative status.

The ARIA Task Force believes it may be possible to take the second
course of action without an HTML Accessibility API Mappings
specification, but such a specification would make the task much
simpler. This document is, of course, not yet available for this
purpose.

This proposal is made by the WAI_PF ARIA Task Force, as discussed in its
regular weekly teleconference on 2 June last, logged at:

http://www.w3.org/2014/06/02-aria-minutes.html

Please reply on list to this email with any objections or concerns.
Silence will be interpreted as ascent, though positive
messages of support are most welcome.

If there are no objections by Close of Business Boston Time Friday 13
June, this CfC will carry, and will be communicated to the HTML-A11Y TF
and the HTML-WG as a formal PF comment and request.

Janina
