PRPC provides features and controls that support the development of accessible applications that can meet the standards of the Web Content Accessibility Guidelines (WCAG) 2.0 AA and Section 508 of the United States Rehabilitation Act.
These standards are an effort to improve web and browser accessibility for people with disabilities. Disabilities can include blindness and low vision, deafness and hearing loss, learning disabilities, cognitive limitations, limited movement, speech disabilities, photosensitivity and combinations of these.
Developers can create work portals that are enabled for accessibility, using composite portals.
See PDN article Make sure your application conforms to accessibility guidelines.
