NSS has provided a set of functions to do the jobs. "GetBestSlot" is a 
preferable function in some situation, such as one crypto device 
environment. "GetBestSlot" provide the simplest way for simple 
application such as mail and ssl. I think, xmlSec will not only run in a 
so simple environment. One day, xmlSec will run in a complex crypto 
environment, such as a key management center or a distributed key 
management system, in which there are so many smart card to read and 
write, so many crypto machine and every crypto machine has more than one 
tokens. "GetBestSlot" will select one from all of those tokens. NSS do 
provides another set of functions operating in that environment, but it 
is not "GetBestSlot".  The new interfaces from the patch try to wrap 
those functions into simple ones. So I still think it is valuable.

BTW, "GetBestSlot" also can work in the above complex envrionment if the 
high level application adjust the behavior of NSS crypto modules. But it 
will affect all of other crypto related applications besides xmlSec. 
It's a bad choice, I think.

Anyway, I will respect you and Tej's viewpoints.

I'll do that.
