[philljenkins]

• New Rule(s): List rule IDs

  • aria_attribute_valid
  • a_link_purpose

• New or modified help files:

  • a_link_purpose

This PR is related to the following issue(s):

• fixes [ACT] Improve ACT mapping for two rules: aria_attribute_valid and a_text_purpose #1760

Additional information can be found here:

• use PR's ACTION artifact: ACT Text Results
• use PR's ACTION artifact: Rule listing

Testing reference:

ACT Text Results:

• no inconsistencies listed for ruleID aria_attribute_valid for ACT 46ca7f (see below)
• no inconsistencies listed for ruleID a_link_purpose for ACT c487ae (see below)

Because mapping to WCAG are not included in ACT Test Results act-report-v2.txt file, you'll have to "test" the mapping by viewing the ruleIDs in the ACTION's Rule listing rules.html file. Look for:

• a_text_purpose is listed (mapped) under 2.4.4 Link Purpose and 4.1.2 Name, Role, Value
• aria_attribute_valid is listed (mapped) under ARIA specification [NA]
