Hello,
I have a question about qualifying elements in the instance that are globally declared in the schema.
I have the two following schemas:
Code:
<xs:schema xmlns:L="HKJ" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="HKJ" elementFormDefault="unqualified" attributeFormDefault="unqualified">
<xs:element name="Root">
<xs:complexType>
<xs:sequence>
<xs:element name="A">
<xs:complexType>
<xs:sequence>
<xs:any namespace="##any" processContents="lax" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="B" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
and
Code:
<xs:schema xmlns:G="XYZ" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="XYZ" elementFormDefault="unqualified" attributeFormDefault="unqualified">
<xs:element name="C">
<xs:complexType>
<xs:sequence>
<xs:element name="D"/>
<xs:element name="E"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
When I create an instance based on Main.xsd schema, using element C as a child of element A (replacing the ##any placeholder), it is valid in XML Spy (and other tools for that matter) with or without the namespace prefix used for element C:
Code:<L:Root xmlns:L="HKJ" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="HKJ Main.xsd"> <A> <G:C xmlns:G="XYZ" xsi:schemaLocation="XYZ Component.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <D/> <E/> </G:C> </A> <B>String</B> </L:Root>
And this is valid as well:
Code:<L:Root xmlns:L="HKJ" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="HKJ Main.xsd"> <A> <C xmlns:G="XYZ" xsi:schemaLocation="XYZ Component.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <D/> <E/> </C> </A> <B>String</B> </L:Root>
Can someone explain why? I always knew that if an element is declared globally in the schema and the namespace is explicit, it has to be qualified in the instance. Why then the <C> without namespace prefix is valid? I’m clearly missing something here.
Thank you for any help,
Ewa
