None of the techniques is normative. Developers are always allowed to use other techniques that meet the success criteria. >For instance, do I violate WCAG 2.0 when I decide NOT to use a ><select> statement for a combo in my application, >and choose instead an input with an associated button and ARIA-Markup? > ><strong> > With other words, is applied ARIA an 1:1 alternative to > <http://www.w3.org/TR/2008/NOTE-WCAG20-TECHS-20081211/H91>http://www.w3.org/TR/2008/NOTE-WCAG20-TECHS-20081211/H91? ></strong> The above technique is just an HTML technique; it does not assume WAI-ARIA. If you don't use a select element but something else combined with WAI-ARIA markup, that construct can only pass WCAG 2.0 if it can be shown that it is accessibility supported (<http://www.w3.org/TR/2008/REC-WCAG20-20081211/#accessibility-supporteddef>) in the human language of the content. If that condition is not fulfilled, the construct can never meet SC 4.1.2. The note to SC 4.1.2 (Name, Role, Value) says: "This success criterion is primarily for Web authors who develop or script their own user interface components. For example, standard HTML controls already meet this success criterion when used according to specification." If you create your own user interface components, you end up at situation D in "Understanding SC 4.1.2" <http://www.w3.org/TR/UNDERSTANDING-WCAG20/ensure-compat-rsv.html>, which has one general technique: <http://www.w3.org/TR/2008/NOTE-WCAG20-TECHS-20081211/G10>.
