This XML file is used to create sequence of accessible name tests. It consist
|
|
of two sections. The first section 'ruledfn' declares name computation rules.
|
|
The second section 'rulesample' defines markup samples we need to check name
|
|
computation rules for.
|
|
|
|
<ruledfn>
|
|
<ruleset>
|
|
<rule>
|
|
|
|
Section 'ruledfn' contains 'ruleset' elements. Every 'ruleset' element is
|
|
presented by 'rule' elements so that sequence of 'rule' elements gives the
|
|
sequence of name computations rules. Every 'rule' element can be one of four
|
|
types.
|
|
|
|
* <rule attr='' type='string'/> used when name is equal to the value of
|
|
attribute presented on the element.
|
|
|
|
Example, 'aria-label' attribute. In this case 'rule' element has 'attr'
|
|
attribute pointing to attribute name and 'type' attribute with 'string'
|
|
value. For example, <rule attr="aria-label" type="string"/>.
|
|
|
|
* <rule attr='' type='ref'/> used when name is calculated from elements that
|
|
are pointed to by attribute value on the element.
|
|
|
|
Example is 'aria-labelledby'. In this case 'rule' element has 'attr'
|
|
attribute holding the sequence of IDs of elements used to compute the name,
|
|
in addition the 'rule' element has 'type' attribute with 'ref' value.
|
|
For example, <rule attr="aria-labelledby" type="ref"/>.
|
|
|
|
* <rule elm='' elmattr=''/> used when name is calculated from another
|
|
element. These attributes are used to find an element by tagname and
|
|
attribute with value equaled to ID of the element. If 'elmattr' is missed
|
|
then element from subtree with the given tagname is used.
|
|
|
|
Example, html:label@for element, <rule elm="label" elmattr="for"/>.
|
|
Example, html:caption element, <rule elm="caption"/>
|
|
|
|
* <rule fromsubtree='true'/> used when name is computed from subtree.
|
|
|
|
Example, html:button. In this case 'rule' element has 'fromsubtree'
|
|
attribute with 'true' value.
|
|
|
|
<rulesample>
|
|
<markup ruleset=''>
|
|
|
|
Section 'rulesample' provides set of markup samples ('markup' elements). Every
|
|
'markup' element contains an element that accessible name will be computed for
|
|
(let's call it test element). In addition the 'markup' element contains some
|
|
other elements from native markup used in name calculation process for test
|
|
element. Test element is pointed to by 'ref' attribute on 'markup' element.
|
|
Also 'markup' element has 'ruleset' attribute to indicate ruleset for the test
|
|
element.
|
|
|
|
How does it work? Let's consider simple example:
|
|
<ruledfn>
|
|
<ruleset id="aria">
|
|
<rule attr="aria-label" type="string"/>
|
|
<rule attr="aria-labelledby" type="ref"/>
|
|
</ruleset>
|
|
</ruledfn>
|
|
<rulesample>
|
|
<markup ref="html:div" ruleset="aria">
|
|
<html:span id="label" textequiv="test2">test2</html:span>
|
|
<html:div aria-label="test1"
|
|
aria-labelledby="label">it's a div</html:div>
|
|
</markup>
|
|
</rulesample>
|
|
|
|
Initially 'markup' element holds markup for all rules specified by 'ruleset'
|
|
attribute. This allows us to check if the sequence of name computation rules
|
|
is correct. Here 'ruleset' element defines two rules. We get the first rule
|
|
which means accesible name is computed from value of 'aria-label' attribute.
|
|
Then we check accessible name for the test element and remove 'aria-label'
|
|
attribute. After we get the second rule which means we should get IDs from
|
|
'aria-labelledby' attribute and compose accessible name from values of
|
|
'textequiv' attributes (that are supposed to give the desired name for each
|
|
element that is being pointed to by aria-labelledby). Check accessible name
|
|
and finish test.
