XML schema: Particle Restriction OK

 

Hi..

       According to schema spec, there are some constraints for a
restriction to be valid.(given under Schema Component Constraint: Particle
Restriction OK (Elt:Elt -- NameAndTypeOK)).

 

When I give a schema which is not correct according to the above
constraints, libxml is not showing any error when it is parsing it.

The document is as follows 

<?xml version="1.0"?>

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"

xmlns:x="http://xsdtesting" targetNamespace="http://xsdtesting"

elementFormDefault="qualified">

        <xsd:complexType name="B">

                <xsd:choice>

                        <xsd:element name="c1" type="xsd:string"/>

                        <xsd:element name="c2"/>

                </xsd:choice>

        </xsd:complexType>

        

        <xsd:complexType name="R">

                <xsd:complexContent>

                        <xsd:restriction base="x:B">

                                <xsd:choice>

                                        <xsd:element name="c6"
type="xsd:int"/>

                                        <xsd:element name="cy8923y219"/>

                                </xsd:choice>

                        </xsd:restriction>

                </xsd:complexContent>

        </xsd:complexType>

        <xsd:element name="elem" type="x:R"/>

        <xsd:element name="doc">

                <xsd:complexType>

                        <xsd:choice>

                                <xsd:element ref="x:elem"/>

                        </xsd:choice>

                </xsd:complexType>

        </xsd:element>

</xsd:schema>

 

Where the restricted element is not correct. 

These constraints are handled in the following functions 

xmlSchemaCheckParticleRangeOK

xmlSchemaCheckRCaseNameAndTypeOK

xmlSchemaCheckRCaseNSCompat

xmlSchemaCheckRCaseRecurseAsIfGroup

xmlSchemaCheckRCaseNSSubset

xmlSchemaCheckCOSParticleRestrict

xmlSchemaCheckRCaseNSRecurseCheckCardinality

xmlSchemaCheckRCaseRecurse

which are under the conditional compilation of the macro
"ENABLE_PARTICLE_RESTRICTION" which is commented.

 

Can you please help me in handling these constraints.

 

 

Thanks and regards,

Bharath.
