Response from the Working Group
================================
Thank you for identifying the duplication. We will add example 2 from
H27 into technique H53 and remove technique H27.

Using technique H53 to meet Success Criterion 1.1.1 is sufficient if
it meets the accessibility supported requirement for conformance. The
technique may be accessibility supported in some environments and not
others. Information on accessibility support is available from
http://www.w3.org/TR/UNDERSTANDING-WCAG20/conformance.html#uc-accessibility-support-head.
