TARGMAX
Certain commands from a client MAY contain multiple targets. This token defines the maximum number of targets may be specified on each of these commands. The value is OPTIONAL and is a set of "cmd:number" pairs, where "cmd" refers to the specific command and "number" refers to the limit for this command.
If the number is not specified for a particular command, then that command does not have a limit on the maximum number of targets. If the "TARGMAX" parameter is not advertised or a value is not sent then a client SHOULD assume that no commands except the "JOIN" and "PART" commands accept multiple parameters.

Format: TARGMAX=[cmd:[number][,cmd:[number][,...]]]
