A customer gave us an xml schema having different default ns and targetNamspace, like that: <xsd:schema xmlns="ProprietaryNamespace" targetNamespace="AnotherProprietaryNamespace" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> ... <xsd:complexType name="complexTypeOne"> <xsd:sequence> ... <xsd:element name="SubElementWithoutPrefix" type="ElementTypeWithoutPrefix" /> <!-- a line with a problem --> </xsd:sequence> </xsd:complexType> ... </xsd:schema> Now we have problem validating values of SubElementWithoutPrefix on different java plattforms. According to the XML schema specification, every element/attribute without namespace prefix belongs to the default namespace. MHK> No, that's not the case. Generally, the "name" attribute contains a local name, which is combined with the targetNamespace of the schema document. Attributes that refer to another schema component, such as "type", are QNames in which no prefix means "default namespace". On the other hand, unqualified elements defined in an xml schema belong to the schemas targetNamespace. MHK> Only if form="qualified" or elementFormDefault="qualified" (which is present in most schema documents but not, apparently, in this one). Without this, a locally-declared element, as here, is in no namespace, it is not in the targetNamespace. So, there is this contradicition to be resolved. When SUNs Java 6 implementation resolves it, SubElementWithoutPrefix belongs to the default namespace. On the other hand, when IBMs java 5 implementation resolves it, SubElementWithoutPrefix belongs to the targetNamespace. How is it defined in XML schema specs? MHK> Neither of the above. SubElementWithoutPrefix should be in no namespace. Regards, Michael Kay http://www.saxonica.com/ http://twitter.com/michaelhkay
