 "select all" flag.

 Thanks.

 in a given layer ?

 In the example in the original report, the `layer` option is used to
 specify the layer to write the categories to, so it cannot be used for
 selection, so there is no "given layer". And since there is no given
 layer, there is no way to determine if the features have category or not.
 So for me the answer for both questions is select regardless of existing
 category. This will do well for simple cases, I'm not sure if there are
 any complicated cases when a more sophisticated approach would be
 appropriate.
