It looks like the return type for most items in the 8.5 API are defined as ArrayOfAnyType which is just defined as a sequence of anyType. This is fine, but when I get a response back, the returned type is not defined anywhere in the API. 
 
For example, if I issue a findGlobalMeetingListByFilter request, I get a findGlobalMeetingListByFilterResponse which contains an ArrayOfAnyType. The array contains objects of type GlobalMeetingInfo, but there is no definition of what a GlobalMeetingInfo object is anywhere in the API that I downloaded. Are these returned types documented anywhere (preferably in a WSDL/XSD)?
