HTML Image Description Extension (longdesc)
Exit Criteria for Candidate Recommendation
The following DRAFT is under consideration by the HTML Accessibility
Task Force (Task Force). The agreed upon text will be submitted to the
HTML Working Group and the Protocols and Formats Working Group for
approval.
Preconditions:
- There is a test
suite.
- The TF agrees that the test suite covers the requirements in the spec
sufficiently.
- The TF agrees that the tests marked "dependent" are sufficient to
show whether an implementation that passes the "required" test also
passes the relevant dependent tests.
Variation on above
The Task Force has developed a suite
of tests to measure support for all normative absolute (RFC2119
"MUST") requirements defined in the specification. The TF agrees that the
tests marked "dependent" are sufficient to show whether an implementation
that passes the "required" test also passes the relevant dependent tests.
The TF agrees that there are sufficient tests for requirements in the
specification labelled should (RFC2119 "SHOULD").
For the HTML 5 Image
Description Extension to be advanced to a W3C Proposed
Recommendation, the following conditions are to be met:
- At least two independent "release" implementations of a user agent
pass each "required" test.
- At least two independent "release" implementations of an authoring
tool pass each "required" test.
- At least one validator can successfully test whether content passes
each "required" test.
- At least one user agent that passes a test passes the relevant
dependent tests.
- At least 50 pages on the Web which are not developed as examples
implement each content requirement.
Variation on above
- At least two independent
implementations of a user agent pass each test for normative
features that are applicable to user agents. (See
Examples)
- At least two independent implementations of an authoring tool
demonstrate support for features that are applicable to authoring tools.
(See Examples)
- At least one validator can successfully test whether content passes
each test for normative
features that can be validated. (See
Examples)
- At least one user agent that passes a test that is dependent an
another, also passes the dependent test. (See
Examples)
- At least 20 pages on the Web which are not developed as examples
successfully demonstrate each content requirement. (See Examples)
