OCL25 — Template return types in operation signatures

Description: At some places, template parameter T appears in operation signatures, e.g., oclAsType(typename:OclType) : T (e.g., Sect. 6.2.1). At other places, this is denoted by "instance of OclType" or <<the return type of the invoked operation>>. It would be more meaningful when these informal return type descriptions are replaced by "OclAny". An additional constraint about the actual return type should be given when necessary.
