Categorisation exercise

Hi everyone,

We had a question on the categorisation exercise at the end of the call: What is a sub-guideline?

The aim is that a sub-guideline is a part (or whole) of a WCAG 2.2 guideline, but broken down by the categories that we defined previously.

The explanation and an example are within the presentation (linked from each template doc):

An example based on alt text

Based on the understanding document, alt text was given functional needs of:

  *   Use without vision
  *   Comprehend Written language - Use with limited ability to,
  *   Math and numeric concepts - Use with limited understanding of,

User needs:

  *   Perceivable > content,
  *   Perceivable > controls

Units of:

  *   Component,
  *   View.
Test types of:

  *   Objective,
  *   Condition.

There didn’t seem to be any point in separating an evaluation by functional need.

In this case, the sub-guidelines were based on trying to make granular evaluations for the units, test types, and user-need, e.g:

  *   Has alt text (component, objective, perceivable content)
  *   Conveys appropriate meaning (component, condition, perceivable content)
  *   Provides descriptive identification (component, condition, perceivable control), could be combined with a guideline on having accnames for controls.
  *   Conveys complex non-text content, e.g. longer description for infographics (view, condition, perceivable content)

For some (e.g. language of the parts), there may not be any useful sub-guidelines, and you could just note in the 1st sub-guideline: no change.

I hope that helps,

-Alastair
