```

## Summary

Interface for parsing OData CSDL (Conceptual Schema Definition Language) XML documents into EDM models.

## Remarks

This interface abstracts the parsing of CSDL XML documents that describe the structure of OData services,
including entity types, complex types, entity containers, and their relationships.
It supports OData specification versions 4.0 and later.
