Rules evaluation and inspection tools from ARIA specs

One of the issues the group needs to discuss is how to enumerate automated rules for checking pages for correct aria implementation.

The testing work group is starting to collect rules for WCAG 2.0 evaluation and we should be contributing rules related to ARIA markup.

For example:
aria-coloindex must be an integer greater than 0
aria-colindex cannot be greater than aria-colcount, unless aria-colcount is unknown (e.g. value -1)

We also have a number of required properties and states for certain widgets and the requirement of an accessible name.

We should consider way to extract and enumerate these requirement from the spec for use as rules by evaluation engines.
