+ | DESCRIPTION |
+ Hi,
+
+ To validate a schema against "schema for schema" for syntactic correctness,
+ I needed to let TraverseSchema class be able to parse "schema for schema".
+
+ I found a problem which relates to the fact that schema for schema contains
+ several utility types not for public use. One example of such utility types
+ is (which is an excerpt from datatypes.xsd):
+
+ <xs:simpleType name="derivationControl">
+ <xs:annotation>
+ <xs:documentation>
+ A utility type, not for public use</xs:documentation>
+ </xs:annotation>
+ <xs:restriction base="xs:NMTOKEN">
+ <xs:enumeration value="substitution"/>
+ <xs:enumeration value="extension"/>
+ <xs:enumeration value="restriction"/>
+ <xs:enumeration value="list"/>
+ <xs:enumeration value="union"/>
+ </xs:restriction>
+ </xs:simpleType>
+
+ To handle utility types, the following changes to TraverseSchema were found to
+ be
+ necessary.
+
+ public DatatypeValidator getDatatypeValidator(String uri, String localpart)
+ {
+
+ DatatypeValidator dv = null;
+
+ if (uri.equals(SchemaSymbols.URI_SCHEMAFORSCHEMA)) {
+ dv = fDatatypeRegistry.getDatatypeValidator( localpart );
+ }
+ /**
+ * tkamiya - 2001-08-06
+ else {
+ dv = fDatatypeRegistry.getDatatypeValidator( uri+","+localpart );
+ }
+ */
+
+ if (dv == null)
+ dv = fDatatypeRegistry.getDatatypeValidator( uri+","+localpart );
+
+ return dv;
+ }
