[idvusers] ISL contourInfo property

IDV list,

I have another question relating to ISL.  I would like to script specific 
contour values on a field using <property name="contourInfo".../>, but since 
the semi-colon separates contourInfo value attributes, you cannot use it like 
it's used in the Contour Properties Editor to specify specific contour values 
like "0.05;0.10;0.25;0.50" for QPF, as an example.  How is this scripted in 
ISL, or can it be??  Thanks,

Mike U
