schema : simpleTypeDecl : derivation : restriction

[Nick Betteridge]

Hi   I'm busy working with xerces (head) for a schema editor and I've got an issue that I'm not too sure if it's a bug or not. The simpleType example I have is contained in the schema below. Take, for instance, simpleType "A". I can quite easily get the enumeration list with a xsSimpleTypeDecl.getLexicalEnumeration();. However, when looking at the xsSimpleTypeDecl.getFinal() to determine if there is a derivation, the result is always 0. Shouldn't this be XSConstants.DERIVATION_RESTRICTION?   Is this a bug or am I making a wrong assumption?   Very grateful for any input.   Thanks   Nick     <?xml version="1.0"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">    <xsd:element name="root">   <xsd:complexType>    <xsd:sequence>     <xsd:element ref="test" minOccurs="0"/>    </xsd:sequence>   </xsd:complexType>  </xsd:element>    <xsd:element name="test" type="A" block="restriction"/>  <xsd:element name="s-a" substitutionGroup="test" />    <xsd:simpleType name="base-A">   <xsd:restriction base="xsd:int">    <xsd:minExclusive value="0"/>    <xsd:maxInclusive value="10"/>   </xsd:restriction>  </xsd:simpleType>    <xsd:simpleType name="base-B">   <xsd:restriction base="xsd:string">    <xsd:minLength value="0"/>    <xsd:maxLength value="10"/>   </xsd:restriction>  </xsd:simpleType>    <xsd:simpleType name="A">   <xsd:restriction base="base-A">    <xsd:enumeration value="1"/>    <xsd:enumeration value="2"/>    <xsd:enumeration value="3"/>    <xsd:enumeration value="4"/>   </xsd:restriction>  </xsd:simpleType>    <xsd:simpleType name="B">   <xsd:restriction base="base-B">    <xsd:enumeration value="a"/>    <xsd:enumeration value="b"/>    <xsd:enumeration value="c123456789"/>   </xsd:restriction>  </xsd:simpleType>    <xsd:simpleType name="Union-A">   <xsd:union memberTypes="A"/>  </xsd:simpleType>    <xsd:simpleType name="Union-AB">   <xsd:union memberTypes="A B"/>  </xsd:simpleType>    <xsd:simpleType name="List-A">   <xsd:list itemType="A"/>  </xsd:simpleType>    <xsd:simpleType name="List-AB">   <xsd:list itemType="Union-AB"/>  </xsd:simpleType>    <xsd:simpleType name="R-A">   <xsd:restriction base="A">    <xsd:enumeration value="1"/>    <xsd:enumeration value="2"/>   </xsd:restriction>   </xsd:simpleType>    <xsd:complexType name="CA">   <xsd:sequence>    <xsd:element name="x" minOccurs="0" maxOccurs="2"/>    <xsd:element name="y" minOccurs="0"/>   </xsd:sequence>  </xsd:complexType>    <xsd:complexType name="R-CA">   <xsd:complexContent>    <xsd:restriction base="CA">     <xsd:sequence>      <xsd:element name="x" minOccurs="1" maxOccurs="1"/>     </xsd:sequence>    </xsd:restriction>    </xsd:complexContent>  </xsd:complexType>    <xsd:complexType name="E-CA">   <xsd:complexContent>    <xsd:extension base="CA">     <xsd:sequence>      <xsd:element name="z"/>     </xsd:sequence>    </xsd:extension>    </xsd:complexContent>  </xsd:complexType>   </xsd:schema>
