Hej,

http://www.w3.org/TR/xmlschema-1/#schema-loc 4) says that no schemaLocation declaration
is allowed to appear, after the namespace has been used for a validation of an element or attribute.

The two instance documents addB162 and addB163 from the schema test suite are defined
as the following:
---------------------------------
<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	  xsi:noNamespaceSchemaLocation="test93490_5.xsd" 	
	  xmlns:foo="foo"
	  xmlns:bar="bar">

	<foo:elem1 xsi:schemaLocation="foo test93490_1.xsd" />
	<bar:elem2 xsi:schemaLocation="bar test93490_3.xsd" />
	<elem2 xsi:schemaLocation="bar test93490_4.xsd" />
</root>
--------------------------------
<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	  xsi:noNamespaceSchemaLocation="test93490_5.xsd" 	
	  xmlns:foo="foo"
	  xmlns:bar="bar">

	<foo:elem1 xsi:schemaLocation="foo test93490_1.xsd" />
	<bar:elem2 xsi:schemaLocation="bar test93490_3.xsd" />
	<elem2>
		<a>
			<b>
				<c xsi:schemaLocation="foo test93490_1.xsd" />
			</b>
		</a>
	</elem2>
</root>
--------------------------------
While the first document is invalid according to the test result and saxon validator, the
second is valid. However they seem to be quite similar to me. In both cases the a
schemaLocation declaration exists after it has been used previously. In the first case
'bar' is reused and in the second 'foo'. The only difference I see is, that the first uses
different locations (test93490_3.xsd vs. test93490_4.xsd) while the second uses the
same (test93490_1.xsd). But is the location used as part of the namespace here?!?

Ciao,
Tobias
