newbie WSDL question: need to merge 2 .wsdl files?

["Thalis A. Kalfigopoulos" <th...@cs.pitt.edu>]

Non-technical question: 
assume I have 2 .wsdl files describing two services A and B. Now I want to present the functions of A & B as a new service C. Can someone give a reason whether the two otiginal .wsdl files for A & B need to be merged into one? They can still be downloaded separately, ran through any tool to generate procedure stubs for the client (which is what the wsdl2java does from what I gathered) and then used in constructing a client to use both A & B as a unified new service C. True of false? Am I missing something?

thanks in advance,
Thalis
