Where is this variable set?

That will be in a subsequent CL and from signaling negotiation.

Could add a comment explaining that this is the value put in the "nomination"
attribute for the next nominated pair when using renomination. Also, based on
the terminology you're using (where "nominating" = something we nominate,
"nominated" = something the peer nominates), should this be called
"nominating_value_"?

Done.

+  // nominated.
