Gregg,



These are clauses appeared in draft 9241-20 relating to cooperation of ATs.



Hajime Yamada





9.1.5 Providing interoperability

ICT equipment and services intended to work with other ICT equipment or
services should not interrupt or invalidate any accessibility-related
functions of these other ICT equipment and services.



EXAMPLE A device has a large number of USB ports so that it can
support the independent connection of a variety of devices simultaneously,
including multiple assistive technologies.



9.3.2 Supporting combinations of assistive technologies

Combinations of multiple assistive technologies should not disturb the
functions of individual assistive technologies.



NOTE 1 This may be achieved by allowing all information to pass through an
assistive technology to any other assistive technologies that are connected
to it.



NOTE 2 If incompatibilities are known, it is important that information
about these incompatibilities is available to the user.



EXAMPLE The outside of a product's packaging clearly lists
incompatibilities.
