UPDF imports the PWGCommon and MediaElements schemas in the UPDFDataTypes schema.  This allows UPDF's data types to be based on and extend the PWG Schema's base types. 2. UPDF names elements and their types either identical to the Semantic Model schemas or - if that is not possible in special cases - use the same naming conventions. 3. UPDF refers to the Semantic Model and Media enumerations of well known values wherever possible. Even if UPDF does not refer to the Semantic Model and Media enumerations/unions 1 to 1, they refer to it and extend it where necessary. 4. UPDF uses a number of data types (e.g. languages, countries, font related lists, etc.), which they propose as an extension to the Semantic Model.
