> <xs:schema xmlns="http://cscB2BCIDXSchemas.Schema1"
> xmlns:b="http://schemas.microsoft.com/BizTalk/2003"
> targetNamespace="http://cscB2BCIDXSchemas.Schema1"
> xmlns:xs="http://www.w3.org/2001/XMLSchema">
> <xs:element name="Root" type="Type1" />
> <xs:element name="Record" type="Type2" />
>
> <xs:complexType name="Type1">
> <xs:simpleContent>
> <xs:extension base="xs:string">
> <xs:attribute name="Field1" type="xs:string" />
> </xs:extension>

> Type1 would have a content type with variety 'Simple', as it

> Therefor the content type of Type2 will be the same as the
> content type of Type1 and both will have the variety of 'Simple'
>
> In Schema 1.1, the content type of Type1 is 'Simple' as well,
> but when constructing the content type of Type2, it seems the
> matching rule is 4.2 and 4.2.1 of the {content type} section
> in http://www.w3.org/TR/xmlschema11-1/#dcl.ctd.ctcc which
> points back to rule 4.1, so Type2 ends up with an 'Empty'
> content type which is wrong IMHO.

> So is that different behaviour in Schema 1.1 intended? Or did
> I follow the wrong path when constructing the types for the
> above schema?
