Hi, Kireeti

On the topic of addresses. I can not figure out
how to advertise different addresses for the case of 
"various components may be numbered differently". 
Do component numbers need to be advertised ? if no, 
what's the purpose of numbering, if yes, how to advertise. 
Can you elaborate ?

Regards,
-Fong
