The first issue was caused by a bug in the Import WSDL wizard - not handling 'simpleType' below 'element' (see http://www.w3schools.com/schema/el_simpletype.asp).
A fix will be included in version 2.1.25.
Meanwhile, attached is a project with the correctly imported WSDL file. The project includes both the WSDL file (OfficeOrderService_v2.wsdl) and the resulting models (in the package XML/fedex.com).
