An OSD-compliant license cannot require that all derivative works be RFC-1234 
compliant because that prevents the Open Source community from using your code 
to create a competing RFC-1235 standard, if someone was motivated to do so.

However, if you provide documentation which claims your source code is 
RFC-1234 compliant, and you request that any modified version retain RFC-1234 
compliance, you'll probably find that most people will be happy to cooperate.
