Review Comment:
I decided to use `json_schema_extra` to be able to keep using rst in
docstring but set a different string in the generated schema.

+Parse a YAML/JSON DAG file into validated :class:`~.models.DagDocument`
objects.
+
+The pydantic models (`.models`) are the schema; this module is the thin I/O +
versioning
+layer around them: it lazily streams each document of a multi-document
YAML/JSON stream (a string or a
+readable file object),
+resolves its `$schema` version against the Cadwyn bundle (migrating an
older-pinned document
+up to head), validates it, and turns pydantic/YAML failures into a readable
+:class:`YamlDagParseError` at the offending document. Parsing is lazy, so
errors surface as
+the iterator is consumed. It is pure (yaml + pydantic + cadwyn; no `airflow`
import), so it is
+unit-testable without a runtime.
