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.

Test 1 :

Procedure

1. The user agent should display the conditional content of the image elements. If the conditional content is rendered automatically through configuration it should appear in place of or next to the image content. If the conditional content is rendered through a query, you will need to query the element properties to render the conditional content (i.e. a context sensitive menu).

Run test

Expected results

1. The alt text--"Three fish swimming"--is accessible to the user.

Test 2 :

Procedure

1. The user agent should display the conditional content of the image elements. If the conditional content is rendered automatically through configuration it should appear in place of or next to the image content. If the conditional content is rendered through a query, you will need to query the element properties to render the conditional content (i.e. a context sensitive menu).

Run test

Expected results

1. The content of the title attribute--"Leaping dolphin"--is accessible to the user.

Test 3 :

Procedure

1. The user agent should display the conditional content of the image elements. If the conditional content is rendered automatically through configuration it should appear in place of or next to the image content. If the conditional content is rendered through a query, you will need to query the element properties to render the conditional content (i.e. a context sensitive menu).

Run test

Expected results

1. The file whose URI is contained by the longdesc attribute is available to the user.
