The only reason there is a CMR-FIELD-TYPE is for java.util.Collection or java.util.Set. If your CMR is return not a single value but collection then the DD lets you specify what is the return type. You dont need the CMR-FIELD-TYPE for a single value return (Say you are returning a
String) This it will get from the abstract method return type.
