Thanks all for answers,
i had some more question:
I use in my application transformation on server. So my style sheets will
"compiled" ones and used more and more. Templates will be compiled at run
time and will be cached.
At the time i cache template objects. So i could use in that case translets
also.
The question that i have are:
1. How long dose it take to create a translet an the fly?? Is it much longer
as create templates in template mode??
2. Are translets threadsafe???
thanks
regards
Dmitri
