UAAG 1.0 Requirement

Checkpoint 2.3 Render conditional content (Priority 1 )
Provision 1 : Allow configuration to provide access to each piece of unrendered conditional content "C".
Provision 2 : When a specification does not explain how to provide access to this content, do so as follows: If C is a summary, title, alternative, description, or expansion of another piece of content D, provide access through at least one of the following mechanisms: (1a) render C in place of D; (2a) render C in addition to D; (3a) provide access to C by allowing the user to query D. In this case, the user agent must also alert the user, on a per-element basis, to the existence of C (so that the user knows to query D); and (4a) allow the user to follow a link to C from the context of D. Otherwise, provide access to C through at least one of the following mechanisms: (1b) render a placeholder for C, and allow the user to view the original author-supplied content associated with each placeholder; (2b) provide access to C by query (e.g., allow the user to query an element for its attributes). In this case, the user agent must also alert the user, on a per-element basis, to the existence of C; and (3b) allow the user to follow a link in context to C.
