How's this; <xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema' xmlns:this='urn:example.org.people' targetNamespace='urn:example.org.people' > <xs:complexType name='person' > <xs:sequence> <xs:element name='given' type='xs:string' /> <xs:element name='family' type='xs:string' /> </xs:sequence> </xs:complexType> <xs:element name='person' type='this:person' /> </xs:schema> It's *both* an element and a complex type.
