Issue #139

I made an attempt to close issue #139 <https://github.com/w3c/personalization-semantics/issues/139> - Update section 3.3 to refer to WCAG 2.1 reference.

I added a short paragraph before the Values table within the purpose section:

Where the same value exists in the WCAG 2.1 Input Purposes for User Interface Components <https://www.w3.org/TR/WCAG21/#input-purposes> values, this specification uses that definition.

 See https://raw.githack.com/w3c/personalization-semantics/issue139/content/index.html#values-1 <https://raw.githack.com/w3c/personalization-semantics/issue139/content/index.html#values-1>

However, we may want this to be an actual citation. If we make this an official citation, we need to add WCAG 2.1 to our References section but I couldn’t figure out how to accomplish that. 

The issue and action remain open.
