Warn when definition labels are not lowercase.

Parameters

There are no options.

Definitions and references are matched together regardless of casing. Using uppercase in definition labels might incorrectly indicate that casing is of importance. Due to this, it’s recommended to use lowercase and turn this rule on.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, remark-lint-definition-case@4, compatible with Node.js 16.
