epf-validate

To validate 1C external data processor XML structure, you can use a validation skill that checks root elements, namespaces, UUID formats, and required blocks like InternalInfo and Properties against platform conventions before loading.

EPF or ERF metadata validation checks root elements, namespaces, version sanity, required blocks, child object ordering, UUID formats, and cross-references to ensure forms and templates exist on disk.

You can check if 1C external report form and template files exist by validating DefaultForm and MainDataCompositionSchema cross-references against declared files relative to the object directory.

1C external processing metadata fails to load when XML structure lacks required namespaces, valid UUIDs, correct child object ordering, or missing form and template files referenced in the metadata.

Yes, you can validate both external data processors (EPF) and external reports (ERF) using the same XML entry point, as the validation logic auto-detects and processes both metadata types.

Automated 1C XML metadata validation is limited to structural checks, UUID rules, and filesystem verification of referenced files; it does not execute the processor or validate business logic inside the 1C platform.
