This read-create string selects an entry in the snmpTargetParamsTable, and that selected entry determines which row of this snmpProxyTable is used to forward a received message. Admins configure it to tie a proxy translation rule to the security and message-processing parameters defined for a particular incoming target. For example, setting this to "paramsIn1" links this proxy row to whatever security model and level are defined under that snmpTargetParamsTable entry.
