Helen is on her way to CSUN, so any comments posted from this address are
just from me!

My comments = CC::, Wendy's comments = WC::

CC::
That makes sense to me, but was a concern of the participants in the study.

WC::

CC::
Are there plans to expand the browser support section? There is a link to
the W3C TR site, but I couldn't (immediately) find anything about browser
support. Is there a specific document (TR) that the Techniques could link
to?

WC::

CC::
Maybe it's worth making these unknowns more explicit. Then authors may be
less surprised if they are informed that elements / attributes are not
supported by the browser they use, and will understand that this is not
predictable.

WC::
>Where possible we have tried to say, "until user agents...."

CC::
Checkpoint 7.4 doesn't currently say this. What should authors do until
user agents support the association of headers and cells? I seem to
remember that there used to be a Technique of using <P> or <BR> in table
cells to to make tables easier (if not accessible) for screen readers.
Could this be recommended until user agents support the association of
headers and cells? Otherwise, an author "must" use attributes that are not
supported by either the main browsers or current screenreaders (I don't
know about other special devices).

WC::

CC::
None of them were observed to use this information (if it was available in
the version they used).  I think more links to this section would be
useful, particularly in the section of the Introduction which indicates
that not all elements / attributes are currently supported.

WC::

CC::
Particpants seemed to be concerned that they would have something 'unknown'
in their page, which didn't work 'now', and they didn't know how a user
might interact with, or whether it might break an older browser.

WC::

CC:
I think this would definitely be worth highlighting.

WC::

CC::
If these are known I think it would be useful.
