I never got a reply on this. Let's please try to solve this 
problem.
Depending on the leakage of version identifiers from client to 
library code (only templates) has severe issues. For example a 
template isn't reinstantiated, if it was already instatiated in 
another module (allinst switch). Also version identifiers work 
globally so you'll probably turn on logging in all libraries you 
use.
