ATAG 2.0 References to WCAG

1. "WCAG" in ATAG 2.0

The Authoring Tools Accessibility Guidelines version 2.0 (ATAG20) refers to the Web Content Accessibility Guidelines (WCAG) without specifying a version number. This allows ATAG 2.0 to remain in effect as new versions of WCAG are released.

The purpose of this document is to provide a bridge between ATAG 2.0 and the most current version of WCAG. This includes:

1. Scheme for determing conformance of Relative Priority ATAG 2.0 checkpoints.
2. Links to techniques for Relative Priority ATAG 2.0 checkpoints.

Note: When performing an ATAG 2.0 conformance assessment for an authoring tool, you must always specify the version of WCAG that was used to determine conformance of the Relative Priority ATAG 2.0 checkpoints.

WCAG 2.0 - W3C Working Draft

Relative Priority Scheme:

WCAG 2.0 establishes four conformance levels for each of its checkpoints: not met, minimum (most important requirements met), level 2 and level 3 (least important requirements met). The ATAG 2.0 relative priority level reflects this as follows:

• Relative Priority 1: The ATAG 2.0 checkpoint satisfies all relevant WCAG 2.0 checkpoint requirements to at least the minimum level.
• Relative Priority 2: The ATAG 2.0 checkpoint satisfies all relevant WCAG 2.0 checkpoint requirements to at least level 2.
• Relative Priority 3: The ATAG 2.0 checkpoint satisfies all relevant WCAG 2.0 checkpoint requirements to at least level 3.

WCAG 1.0 - W3C Recommendation

Relative Priority Scheme:

WCAG 1.0 establishes three priority levels: Priority 1 (most important requirements), Priority 2 and Priority 3 (least important requirements). The ATAG 2.0 relative priority level reflects this as follows:

• Relative Priority 1: The ATAG 2.0 checkpoint satisfies all relevant WCAG 1.0 Priority 1 checkpoints.
• Relative Priority 2: The ATAG 2.0 checkpoint satisfies all relevant WCAG 1.0 Priority 1 and 2 checkpoints.
• Relative Priority 3: The ATAG 2.0 checkpoint satisfies all relevant WCAG 1.0 checkpoints.
