Thanks Ian,

The patterns type looks like this:

<xs:complexType name="patternsType">
  <xs:sequence>
    <xs:element name="pattern" type="xs:string" maxOccurs="unbounded"/>
  </xs:sequence>
</xs:complexType>

nothing fancy.

I've since triple checked the schema using:

o IBM SQC 2.0
o XML Spy 4.4
o Xerces 2.0.2

It passes them all with flying colours so I guess it's possibly a bug in
Xerces 1. I submitted it to them and I'm awaiting a response.
