can layers be linked?

[LITTLE Nelson]

Hi,

 

I would like to link two layers of different geometry types. 1 layer
contains points, the other layer contains lines. The points and lines
are shown together to display a composite object on a map. If the user
no longer wants to see that composite object on the map then I would
like to turn off both of the layers. I am sure I can do it
programmatically, but I would like to know if they can be linked in the
MapFile? 

 

Thanks,

Nelson
