"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.
