OK, I figured it out. :-) Turns out the response was NOT valid  
according to the schema. It was missing a required element  
"Accommodation" deep down in PackageReservation/Package/ItineraryItems/ 
ItineraryItem.

So I guess the real question is: why was the client telling me that it  
was having a problem finding a choice for the wrong element? And how  
did this pass the server-side check? I thought it was more stringent  
about these things? On my side, I'll dig into the schemas and see if  
Accommodation was required or optional and any other relevant bits.
