Multiple Values for a Property?

[sunthas]

This question has to do with the bags mod I was playing with. Talyns was helping me quite a bit on this.

He said to put 3 values in one property called OnShow

Parent.MinimumSize=178,62
Parent.MaximumSize=178,62
Parent.Size=178,62

What seperator do I use to get all 3 of these into that one Property. I've looked through lots of the XML files and it seems they are all 1 to 1.
