Windchill Parameters - Queries on Advanced Logic Selection

Hello Community,

I added few parameters to my assembly and did Configure action. I stumbled upon the below queries, please shed some light if you can.

i) If a Parameter is not mapped to any attribute, does it still have any significance? If yes, please explain how. 

ii) As per below statement from PTC, what is the purpose of adding parameters after the page break?

If at least one page break has been defined for the topmost configurable module, then only the input parameters for the first page of this configurable module are processed.

iii)Statement: Adding child resolution would process the parameters for the child configurable module first. Query: I see the child parameters and parent parameters appearing in the same page of Set Parameters tab, then how the process is done first for the child?

Thanks in advance.
