How can I design my
xsd to ignore the sequence of elements?
<root> <a/> <b/> </root>
<root> <b/> <a/> </root>
I need to use extension for code generation reasons, so I tried the following using all:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="http://www.example.com/test"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:t="http://www.example.com/test" >
<xs:complexType name="BaseType">
<xs:all>
<xs:element name="a" type="xs:string" />
</xs:all>
</xs:complexType>
<xs:complexType name="ExtendedType">
<xs:complexContent>
<xs:extension base="t:BaseType">
<xs:all> <!-- ERROR -->
<xs:element name="b" type="xs:string" />
</xs:all>
</xs:extension>
</xs:complexContent>
</xs:complexType>
<xs:element name="root" type="t:ExtendedType"></xs:element>
</xs:schema>
This
xsd is not valid though, the following error is reported at <!-- ERROR -->:
cos-all-limited.1.2: An all model group must appear in a particle with {min occurs} = {max occurs} = 1, and that particle must be part of a pair which constitutes the {content type} of a complex type definition.
Documentation of cos-all-limited.1.2 says:
1.2 the {term} property of a particle with {max occurs}=1 which is part of a pair which constitutes the {content type} of a complex type definition.
I don't really understand this (neither
xsd nor English native speaker :) ).
Am I doing the wrong thing, am I doing the right thing wrong, or is there no way to achieve this?
Thanks!
