The OPA project that I am working on needs to be meet the web standards of the Government of Canada, this includes accessibility requirements for the blind, etc. (Web Standards for the Government of Canada - Treasury Board of Canada Secretariat)
Does anyone know if OPA is compatible with assistive technologies for those who are disabled? such a screen readers, etc.?
Yep. Have a look at the Product Accessibility information here:
(scroll down to see the Oracle Policy Automation entries)
Hope that has the info you need,
