This sentence seems to imply that it is even possible. Based on my reading of http://www.w3.org/TR/xmlschema-1/#Type_Derivation (esp. 2.2.1.1 through 2.2.1.3) I would have thought that it isn't. The text says that all simple types are derivations (direct or not) of anySimpleType. Inserting a complex type in there would effectively change that. Not that the spec isn't already baroque enough as it is. <element name='time'> <choice> <text/> <group> <element name='hour'><text/></element> <element name='min'><text/></element> </group> </choice> </element> Ah well. -- Robin Berjon <robin.berjon@e...> Research Scientist, Expway http://expway.com/ 7FC0 6F5F D864 EFB8 08CE 8E74 58E6 D5DB 4889 2488
