[LEAPSECS] ITU Radiocommunication Assembly voting procedure

[Gerard Ashton]

A question that arose at the Wikipedia "Leap second" article is what is 
the voting procedure
for the 2012 Radiocommuication Assembly? What percent must vote in the 
affirmative?
Is it the required percent of member states, member states present, or 
member states
that vote (where an abstention is not a vote). If there are a large 
number of absences
or abstentions, does that change anything?
