[Octave-bug-tracker] [bug #48439] validateattributes throws errors without IDs

[Carlo de Falco]

Follow-up Comment #2, bug #48439 (project octave):

Lachlan,

The error is an invalid input argument in both cases,
and the error message does specify whether the invalid arg 
was passed to validateattributes itself or to a function using
validateattributes internally, so I think that part is not that bad ...

But MATLAB is even more specific, as it has a different identifier for each
kind of test that validateattributes can perform on inputs, e.g.
'MATLAB:notLessEqual' if the input is required to be less or equal than a
specified value but it isn't or 'MATLAB:invalidType' if it is not of one of
the allowed types.

I am not limited to existing IDs but I remember previous discussions about not
introducing too many different IDs and this would probably introduce a lot.
