Input constraints used

This is an in-progress draft. The content is incomplete and could change substantially.

Core requirement developing

Field constraints and conditions are available.

Methods

HTML: To programmatically indicate, use the pattern attribute or write the information in a label; to visually indicate, add the requirements to the page near the input.

Recommended Practices

The constraints remain persistent.

Tests

Procedure

For each input:

Confirm it has a visual information that describes the constraint.
Inspect the code and accessibility tree (when applicable) and confirm that the constraint is programmatically listed in the code and associated with the input.

Expected results

#1 and #2 are true.
