Seeking inputs for update to EPUB Accessibility techniques.

EPUB Accessibility conformance and Discovery 1.0 is the first specification that defines the requirements for accessible EPUB publication. The specification is at the abstract layer to reduce dependency on technology and formats.
And the specific guidance is provided by non-normative techniques, (hyperlink at 1). This design allows more rapid updates to the techniques without changing the abstract layer of the specifications, so that the techniques can be updated with the changing technology or changing environment.
We would like to start the process of updating the EPUB accessibility techniques and would like to invite your valuable inputs for it.
