src-ct.2.1: Complex Type Definition Representation Error for type 'aa....aa'. When <simpleContent> is used, the base type must be a complexType whose content type is simple, or, only if restriction is specified, a complex type with mixed content and emptiable particle, or, only if extension is specified, a simple type. 'bb....bb' satisfies none of these conditions.
