1) Statements of sufficiency should be in a note - not in the
provision.
2) Statements of sufficiency cannot contradict the provision. They
must explain something that is already allowed by the provision.
Current proposed language.
Size, shape, location - Instructions provided for understanding information
and operating user interfaces do not rely on shape, size, visual location,
or orientation of components. Additional information for use by assistive
technologies - such as alternate text to describe necessary visual cues, or
programmatic encoding of relationships between objects that is necessary for
understanding and operating the content - is sufficient.
Suggested edit
Size, shape, location - Instructions provided for understanding information
and operating user interfaces do not rely on shape, size, visual location,
or orientation of components.
NOTE: Additional instructions available to assistive technologies used by
those who cannot see shape, size, visual location, or orientation - such as
alternate text to describe necessary visual cues, or programmatic encoding
of relationships between objects that is necessary for understanding and
operating the content - qualifies as instructions for meeting this
provision.
