indeed, I checked the sources, SR core tries to convert the str to int 
and fails in above case.

I can make a patch so to return true for PV is they have a value with 
len!=0, if feels to be right for the rest -- it is what I would expect 
as well.

However, maybe Andrei can detail more about the logic behind.

Cheers,
