[sca-assembly] [NEW ISSUE] Duplicated atributes in sca-binding-sca.xsd and sca-implementation-composite.xsd

Title: [sca-assembly] [NEW ISSUE] Duplicated atributes in sca-binding-sca.xsd and sca-implementation-composite.xsd

Raiser:                             Plamen Pavlov

Target:                             SCA Assembly Specification

Description:                    

When SchemaFactory is created, based on the on the SCA XSD documents

e.g.

SchemaFactory schemaFactory = SchemaFactory.newInstance( XMLConstants.W3C_XML_SCHEMA_NS_URI );

return schemaFactory.newSchema( docs );

several exceptions are thrown

…./sca-binding-sca.xsd:

•       ct-props-correct.4: Error for type 'SCABinding'. Duplicate attribute uses with the same name and target namespace are specified.  Name of duplicate attribute use is 'uri'.

•       e-props-correct.4: The {type definition} of element 'binding.sca' is not validly derived from the {type definition} of the substitutionHead 'sca:binding', or the {substitution group exclusions} property of 'sca:binding' does not allow this derivation.

…./sca-implementation-composite.xsd:

•       ct-props-correct.4: Error for type 'SCAImplementation'. Duplicate attribute uses with the same name and target namespace are specified.  Name of duplicate attribute use is 'requires'.

•       e-props-correct.4: The {type definition} of element 'implementation.composite' is not validly derived from the {type definition} of the substitutionHead 'sca:implementation', or the {substitution group exclusions} property of 'sca:implementation' does not allow this derivation.

The problem is duplication of some attributes in the base and in the extension types.

Here are the XSD snippets which caused these problems:

<complexType name="Binding" abstract="true">

<sequence>

<element name="operation" type="sca:Operation" minOccurs="0" maxOccurs="unbounded" />

</sequence>

<attribute name="uri" type="anyURI" use="optional"/>

<attribute name="name" type="NCName" use="optional"/>

<attribute name="requires" type="sca:listOfQNames" use="optional"/>

<attribute name="policySets" type="sca:listOfQNames" use="optional"/>

</complexType>

<complexType name="SCABinding">

<complexContent>

<extension base="sca:Binding">

<sequence>

<element name="operation" type="sca:Operation" minOccurs="0" maxOccurs="unbounded" />

</sequence>

<attribute name="uri" type="anyURI" use="optional"/>

<attribute name="name" type="QName" use="optional"/>

<attribute name="requires" type="sca:listOfQNames" use="optional"/>

<attribute name="policySets" type="sca:listOfQNames" use="optional"/>

<anyAttribute namespace="##any" processContents="lax"/>

</extension>

</complexContent>

</complexType>

<complexType name="Implementation" abstract="true">

<attribute name="requires" type="sca:listOfQNames" use="optional"/>

<attribute name="policySets" type="sca:listOfQNames" use="optional"/>

</complexType>

<complexType name="SCAImplementation">

<complexContent>

<extension base="sca:Implementation">

<sequence>

<any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded"/>

</sequence>

<attribute name="name" type="QName" use="required"/>

<attribute name="requires" type="sca:listOfQNames" use="optional"/>

<attribute name="policySets" type="sca:listOfQNames" use="optional"/>

<anyAttribute namespace="##any" processContents="lax"/>

</extension>

</complexContent>

</complexType>

Proposal: Remove the duplicated attributes from the extension complex types.
