I'm not sure if attributes for zip can have the same value or
not. Still I agree with you from the results of my own tests. To me it seems
like the validation only checks to see if the XML schema is valid xml or not. It
does not check if the xml document is formatted correctly according to the
schema.
A simple example which is validated with no
errors:
first.xml
------------
<?xml version="1.0"
encoding="UTF-8"?>
<test_root
xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="first.xsd">
<name>Peter Tornberg</name>
<address>Home</address>
<age>100</age>
</test_root>
first.xsd
------------
<?xml version="1.0"
encoding="UTF-8"?>
<xsd:schema
xmlns:xsd="http://www.w3.org/2000/10/XMLSchema">
<xsd:element
name="test_root">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="failure"
type="xsd:string"/>
<xsd:element name="name"
type="xsd:string"/>
<xsd:element name="address"
type="xsd:string"/>
<xsd:element name="age"
type="xsd:integer"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>

I've been trying to get validation to
fail after violating the unique requirement in a schema, and it doesn't seem
to fail no matter what I do. I took the example from the Schema primer
too, and it fails. I see that support is still experimental. Is
this not yet supported or am I doing something wrong? I've included
the schema and the document that I thought would fail validation because of
the duplication within the code attribute of zip. But it passes just
fine?
Thanks,
Rebekah
