Please be aware of the following limitations in the use of FAE:

  • While passing all of the FAE rules will generally improve the accessibility of web pages, it should not be inferred from this that all WCAG 2.0 Level A and AA accessibility requirements have been met. We encourage you to become familiar with all the accessibility requirements of WCAG 2.0 and to be sure to implement them in your designs, including requirements that can only be tested manually. FAE identifies in the report many of the manual checks you will need to perform or account for in your design and qaulity assurance requirements.
  • FAE and its test components may not be able to interpret all markup; we recommend that you validate your documents to improve the ability of FAE to interpret markup.
  • If you are using accessibility techniques for conforming to WCAG 2.0 that are not identified in a ruleset, this may result in not passing some of the rules used for evaluating accessibility.
