HTML Legend opt_flag=13 for Class block not working?

[Ei Fujioka]

Thanks, Daniel, for taking your time and what a quick response!

Yeah, I thought they were typos. It is under "ClASS block" and still keeps
saying "layer"... But it also states "e.g. opt_flag=14 (shown below) means
do not show classes in the legend that are out of scale." 
So probably this parameter was originally planned for classes as well??

Anyway, good to know.

It would be great if this parameter is actually implemented for classes.

Thanks.
