Altova Mailing List Archives>Archive Index >xml-dev Archive Home >Recent entries >Thread Prev - [xml-dev] targetNamespace vs default namespace >Thread Next - RE: [xml-dev] targetNamespace vs default namespace Re: [xml-dev] targetNamespace vs default namespaceTo: REV Tamas <tamas.rev@-----.---> Date: 7/6/2009 11:04:00 PM Michael and Pete have already supplied answers to your question, but I
thought it might help to explicitly clarify one additional point --
which is to differentiate the default behavior between declaration and
reference. In this example:
<xsd:complexType name="complexTypeOne">
<xsd:sequence>
...
<xsd:element name="SubElementWithoutPrefix"
type="ElementTypeWithoutPrefix" /> <!-- a line with
a problem -->
</xsd:sequence>
</xsd:complexType>
"SubElementWithoutPrefix" is a local element *declaration*. Because
the <schema> declaration specifies elementFormDefault="qualified",
this element is in the targetNamespace. (If you didn't have
elementFormDefault="qualified", it would be in no namespace.)
"ElementTypeWithoutPrefix" is a type *reference*. Because no prefix is
explicitly specified, the type is from the default namespace.
Defining elements in a different namespace from their types is a
fairly common practice.
The Sun Java 6 validation is in error. The IBM Java 5 validation is correct.
