// SOAP arrays are declared as follows (unimportant fields ellided):
//
// 	<xs:complexType name="Array">
// 	  <xs:attribute name="arrayType" type="xs:string" />
// 	  <xs:any namespace="##any" minOccurs="0" maxOccurs="unbounded" />
// 	</xs:complexType>
//
// Then schemas that want to declare a fixed-type soap array do so like this:
//
// 	<xs:complexType name="IntArray">
// 	  <xs:complexContent>
// 	    <xs:restriction base="soapenc:Array>
// 	      <xs:attribute ref="soapenc:arrayType" wsdl:arrayType="xs:int[]" />
// 	    </xs:restriction>
// 	  </xs:complexContent>
// 	</xs:complexType>
//
// XML Schema is wonderful, aint it?
