Anytype prevent identity constraint application
-----------------------------------------------
Key: XERCESC-1884
URL: https://issues.apache.org/jira/browse/XERCESC-1884
Project: Xerces-C++
Issue Type: Bug
Components: Validating Parser (XML Schema)
Affects Versions: 2.7.0
Environment: Linux 2.6.5-7.244-smp x86_64 GNU/Linux
Reporter: Thomas Carcaud
Priority: Minor
Attachments: anytype_prevent_id_constraint.xml,
anytype_prevent_id_constraint.xsd
ID declaration is not found when it is enclosed in two levels of anytype
elements.
In this example :
<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
elementFormDefault="qualified">
<xs:element name="bigBadWolf">
<xs:complexType>
<xs:sequence maxOccurs="unbounded">
<xs:element name="eat">
<xs:complexType>
<xs:attribute name="ref" type="xs:IDREF"/>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="littlePig">
<xs:complexType>
<xs:attribute name="id" type="xs:ID"/>
</xs:complexType>
</xs:element>
<xs:element name="world">
<xs:complexType>
<xs:all>
<xs:element name="strawHouse"/>
<xs:element name="stickHouse"/>
<xs:element name="brickHouse"/>
<xs:element ref="bigBadWolf"/>
</xs:all>
</xs:complexType>
</xs:element>
</xs:schema>
<?xml version="1.0" encoding="UTF-8"?>
<world xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="anytype_prevent_id_constraint.xsd">
<strawHouse>
<littlePig id="first"/>
</strawHouse>
<stickHouse>
<littlePig id="second"/>
</stickHouse>
<brickHouse>
<thickWall>
<littlePig id="third"/>
</thickWall>
</brickHouse>
<bigBadWolf>
<eat ref="first"/>
<eat ref="second"/>
<eat ref="third"/>
</bigBadWolf>
</world>
Validation fails with error "ID attribute 'third' was referenced but never
declared". Same kind of problem can be reproduced with unique/key and keyref
and it also prevent duplicate id detection.
>From my investigations in IGXMLScanner , at the brickHouse level, modelType ==
>SchemaElementDecl::Any will set laxThisOne to true. Then at the thickWall
>level, laxThisOne set fValidate to false. And this disable the call to
>fICHandler->activateIdentityConstraint.
My text editor using XercesJ 2.9.1 does not suffer from this bug.
