Re: More metadata questions

Hi John

I think we can also file issue regarding the questions then we will not
forget document it. The spec on github is here
https://github.com/w3c/epub-specs/blob/main/epub33/a11y/index.html so we
can file issue under that github repo (
https://github.com/w3c/epub-specs/issues/). Please let us know if need help
creating github issue.

George and some of PCG members are also working on accessibilitySummary as
a sub-taskforce I think this could be very useful input. In terms of wcag
version it is covered here
https://www.w3.org/TR/epub-a11y-11/#example-a-basic-conformance-statement
but I also feel how to describe it as human readable format in
accessibilitySummary could be a bit more clear. I look forward to further
discussion in tmr meeting or the accessibilitySummary sub-TF meetings.

Cheers,
Zheng
