The below is selectors that are extended by markuplint:

Selector Type	Code Example
ARIA pseudo-class	`:aria(has name)`
ARIA Role pseudo-class	`:role(heading)`
Content Model pseudo-class	`:model(interactive)`

ARIA pseudo-class

:aria(syntax)

Syntax	Example	Description
`has name`	`:aria(has name)`	Matches the element has accessible name
`has no name`	`:aria(has no name)`	Matches the element has no accessible name

ARIA Role pseudo-class

:role(roleName)
:role(roleName|version)

You can specify the version of WAI-ARIA by separating the pipe like :role(form|1.1).

Content Model pseudo-class

:model(interactive)
:model(palpable)

For example, :role(interactive) matches <a>(with href attr), <button>, and so on.

  "attrValue": "/^[a-z]+$/"
}
