   (a) Manufacturers and service providers shall evaluate the accessibility,

   are conducted, including individuals with disabilities in such activities;

   (3) Working cooperatively with appropriate disability-related organizations;
   and

   (4) Making reasonable efforts to validate any unproven access solutions
   through testing with individuals with disabilities or with appropriate
   disability-related  organizations that have established expertise with
   individuals with disabilities.
