What the Validator Does

This validation system provides a simple tool for checking whether an OEB document or package meets most (but not all) of the conformance requirements spelled out in the Open eBook Publication Structure Specification. Please read the annotated copy of the conformance requirements to determine exactly which requirements are checked.

The validator also provides warnings about elements and attributes listed as deprecated or discouraged in the OEB Publication Structure Specification, sections 3.6 to 3.59.

Documents that pass this facility's checks should have an extremely high level of portability and compatibility with a wide range of HTML and XML tools. Such documents are also likely to upgrade smoothly to future versions of the OEB specification.
