Restrictions involving two levels of substitution groups raise false errors
---------------------------------------------------------------------------
Key: XERCESJ-1215
URL: http://issues.apache.org/jira/browse/XERCESJ-1215
Project: Xerces2-J
Issue Type: Bug
Components: XML Schema Structures
Affects Versions: 2.8.1
Reporter: Eric van der Vlist
The following schema:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="head" type="xs:token"/>
<xs:element name="subHead" type="xs:token" substitutionGroup="head"/>
<xs:element name="subMember" type="xs:token" substitutionGroup="subHead"/>
<xs:complexType name="baseType">
<xs:sequence>
<xs:element ref="head"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="restrictionType">
<xs:complexContent>
<xs:restriction base="baseType">
<xs:sequence>
<xs:element ref="subHead"/>
</xs:sequence>
</xs:restriction>
</xs:complexContent>
</xs:complexType>
</xs:schema>
Raises the following errors:
SystemID: /home/vdv/wadi/repro1.xsd
Endroit: 21:42
Description: rcase-RecurseLax.2: There is not a complete functional mapping
between the particles.
URL: http://www.w3.org/TR/xmlschema-1/#rcase-RecurseLax
SystemID: /home/vdv/wadi/repro1.xsd
Endroit: 21:42
Description: derivation-ok-restriction.5.4.2: Error for type 'restrictionType'.
The particle of the type is not a valid restriction of the particle of the
base.
URL: http://www.w3.org/TR/xmlschema-1/#derivation-ok-restriction
Note that this functionnaly equivalent schema:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="head" type="xs:token"/>
<xs:element name="subHead" type="xs:token" substitutionGroup="head"/>
<xs:element name="subMember" type="xs:token" substitutionGroup="head"/>
<xs:complexType name="baseType">
<xs:sequence>
<xs:element ref="head"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="restrictionType">
<xs:complexContent>
<xs:restriction base="baseType">
<xs:sequence>
<xs:choice>
<xs:element ref="subHead"/>
<xs:element ref="subMember"/>
</xs:choice>
</xs:sequence>
</xs:restriction>
</xs:complexContent>
</xs:complexType>
</xs:schema>
Is considered valid.
Thanks,
Eric
