You can register the class but with the "visible=0" paramter.

Alternatively, you can use the old "misc" feature:

"misc" is a dictionary mapping ids to objects (e.g. "ImageFile" objects).
When the product initialization code find a "misc" variable
in the module, it publishes its content under:

   /misc_/<product_name>/id

You can then define "icon= '/misc_/<product_name>/id'"
in your class.
