Subject: [mpls] Doubt related to RFC 5036

hello all,
Can anybody help in understanding the statement in RFC 5036
"A FEC is a list of  one or more FEC elemets".
For example,
If there are three LDP enabled routers A--B--C.
50.50.50.1 ,50.50.50.2, 50.50.50.3 , 50.50.50.4 are the four /32 host connetced to the router C.
Router C will advertise four label associated with four /32 host.
So in the label mapping message,can router C aggregrate all the four FEC TLV and associated label with it or not?
will all four mentioned /32 host will be called FEC element of a FEC??
Can i really club the label mapping messages and send in one label mapping message??please help me to understand this.  
If we really can do this then in that case label mapping message should have a list of hop count TLV too,which is not specified in RFC.
