Data Guard Broker 10.2.0.3 and log_archive_dest_n

Hello all!
I am playing with data guard broker 10.2.0.3 and a physical standby. I must admit the product is not bad, and it potentially helps operators to seamlessly perform switchovers. Switchovers are now reduced to a one liner, neat!
However, one thing is quite odd: in the databases' v$parameter views on primary and standby I don't find a value for log_archive_dest_n. Here you'd normally see a value similar to "service=myServiceDescriptor LGWR ASYNC valid_for(....." but not in my case. I know the settings are working (show configuration in DGMGRL) but that's still quite surprising. I also see lines beginning with "alter system set log_archive_dest_2=..." but why don't they appear in v$parameter? I have done a quick search on Metalink but did not find anything related to this feature. 

Has anybody seen this before? Is it a bug?
BTW, running 10.2.0.3 EE on paravirtualised RHEL 4U6 32bit based on Oracle VM. 

Thanks for all your suggestions.

Martin
