Selection
Set1
All the <Hx> tags where x is comprise between 1 and 6 and all the tags with a "role" attribute equals to "heading" and an "aria-level" attribute (h1, h2, h3, h4, h5, h6, [role=heading][aria-level])

For each element of Set1, we check whether the content of the tag is pertinent (see Notes about relevancy detection).
For each element returning false in Test1, raise a MessageA. Raise a MessageB instead.
MessageA : Not pertinent heading
- code : NotPertinentHeading
- status: Failed
- parameter : tag text, tag name, snippet
- present in source : yes
MessageB : Check heading pertinence
- code : CheckHeadingPertinence
- status: Pre-Qualified
- parameter : tag text, tag name, snippet
- present in source : yes
