Heading is descriptive needs improvements

[rvantonisse]

During several audits with this rule, “Heading is Descriptive”, we encountered some situations in which we were forced by the rule to fail the SC.

The stituations were:

1. Empty heading with a section of the content.
2. Heading without section of the content
3. Heading that describes only a part of the section of the content.

We believe these situations should not fail the WCAG SC 2.4.6 and therefore the rule needs some improvements.

Applicability

This rule applies to any non-empty element with the semantic role of heading that is either visible or included in the accessibility tree.

Expectation

Each target element describes the topic or purpose of a part of its section of the content or has no section of the content.

We've updated the heading is descriptive rule quite a bit. I believe these issues are resolved.
