This looks correct (from visual inspection).
 
To run it you will need Saxon 9.2 or the development version of Xerces (I
can't speak for Xerces). Most schema tools do not yet support XSD 1.1, and
both these two are incomplete implementations.
 
You don't need to change the xs:schema element in order to use XSD 1.1. All
you need to do is to use an XSD 1.1 processor.

Hi, Michael

Would it be something like this?
<xs:attribute name="attribute_id" use="required">
   <xs:simpleType>
       <xs:restriction base="xs:string">                   

           <xs:assert test="@attribute_id=Attributes/Attribute/@id or
@attribute_id='id'"> 
       </xs:restriction>
   </xs:simpleType>
</xs:attribute>

We are using saxon8 to parse and eclipse and altova xml spy to edit xml.
Are they support 1.1?

Is 1.1 backward compatible with 1.0? I mean: is it enough to change the
header of the xml and xsd or the whole xsd and xml should have been changed?

Is this the correct header for xsd?
<?xml version="1.1" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault=" 
unqualified">

Because both eclipse and xml spy says that it is not valid.

Thanks for help.

Regards:
   Bence

I don't think this can be done in XSD 1.0

It can be done in XSD 1.1, of course, using assertions.
