At the end of the * day, we look for unmarked customizations and raise errors for them. * * <p> * Between this approach and the JAXB spec 1.0 is a problem that * the spec allows/prohibits customizations at schema element level, * while BGMBuilder and XSOM works on schema component levels. * * <p> * For example, a property customization is allowed on a complex type * schema component, but it's only allowed on the <complexType> * element. The spec team informed us that they would consider resolving * this discrepancy in favor of RI, but meanwhile we need to detect * errors correctly. * * <p> * This filter is implemented for this purpose. * * * <h2>Customization and allowed locations * * - globalBinding/schemaBinding * schema * * - class * complexType(*), modelGroupDecl, modelGroup, element * * - property * attribute, element, any, modelGroup, modelGroupRef, complexType(*) * * - javaType * simpleType(*) * * - typesafeEnumClass * simpleType(*) * * - typesafeEnumMember * simpleType(*), enumeration * * Components marked with '*' needs a check by this component * since more than one schema element corresponds to one schema component * of that type. * * <p> * For simple types, customizations are allowed only under the <xs:simpleType> * element, and for complex types they are allowed only under the * <xs:cimplexType> element. * * <p> * So the bottom line is that it would be suffice if we just make sure * that no customization will be attached under other elements of * simple types and complex types.
