Sets of n values are represented by a sequence of parameters whose
parameter name is omitted for parameters 2 through n.
In the example in the minutes:
"job-name 3 foocopies 1 2document-format 22 application/postscript"
"finishings 5 staple 5 punch" CRLF
finishings is a set consisting of "staple" and "punch".
I hope this example helps.
