how can two versions of same DS Component coexist ?

[Hawk Osgi]

Hi,

I'm learning OSGi, I know that I can install different versions of same bundle 
but can't find anything in spec about component version.

I installed two versions 1.0.0 and 2.0.0 of a same bundle that contains one DS 
component. 

But when I tried to activate them I got a message complaining about the 
duplicated names.


there are a way tohave two versions of same component activated?

thanks
