In the GNML tags for variable GNML styles, parameters are to be specified with operators #1, #2..#9 and #A for tenth parameter. You can't specify more than 10 parameters.

The parameter ordinal number in tags code (2) must correspond to the ordinal number of parameters in the list (1).

#1 corresponds to the value of the 'weight' parameter, #2 corresponds to the value of the 'left margin' parameter, etc.
