Update parsers documentation

**Description**
Currently parsers lacks proper sorting support.

**Proposed solution**
Add configurable sorting with sensible defaults.

**Priority**: Low/Medium

The issue does not name a file, test, or entry point. First locate the parsers documentation and the current parser sorting behavior, then determine how configuration and defaults are represented. Done means the documentation and parser behavior clearly support configurable sorting with sensible defaults.
