IMHO, it would be a good idea if we could separate the QF engine and the FIX classes 
completely, ie have a engine package and a package (library, dll, jar) for each FIX 
4.0-4.4. The generation scripts could be part of the engine package and generate the FIX 
message package out of the data dictionary. In the end, you would have (for C++):

	libquickfix.so + libquickfix_fix42.so etc.

Correspondingly for the other APIs.

This make the handling of custom messages or fields much easier: The user just takes the 
basic QF engine, sets up its own data dictionary and generates/builds the message package.

What do you think?

Yes, browsing the source code I saw this could be an option, but did not check in detail.
