Hi Jason,

I think I will re-implement it in java PsBase2, but will probably won't 
do it for base 1, so we can treat it as new feature without backward 
compatibility.

You're right, using multiple parameters is the simplest way. However 
this will impact on LS implementation (timeouts) and perhaps on other 
services (MA?), so we need to tell other people about the change.

I added Roman to CC, he was involved to supportedEventTypes changes, so 
perhaps he has some considerations about it.
