Let me clarify what sort of a precedent I meant.

I agree that the XForms specification does not (and should not)
require host languages to implement the 'accesskey' feature as
described or any other specific implementation of the required
capability.

On the other hand, the PF WG requested from the Forms WG that a
proviso be added to the description of ACCESSKEY specifically
mentioning the need to afford the user review and configuration of
key bindings, if key-bindings were to be indicated by the author.

Yes, the definition was 'roughly' taken from prior format
specifications, but the _refinement_ to make explicit mention of this
user capability was no accident, no 'roughness' in the heredity from
those specifications. It was the results of comparison with the UAAG
and discussion between the WAI and the WG producing the spec.

So it sets a precedent to the extent that one should reasonably expect
the WAI, presented with another format implementing an accesskey-like
function, to demand that the user ability to review and re-bind to alternate
input events be part of the specification.

I would have had a precedent to cite in normative text but for an
editorial error in the production of the SMIL 2.0. But a miss is as
good as a mile when I need a publicly accessible reference.

I hope this clarification meets your approval.
