How to use the nifgen.errors.InvalidRepeatedCapabilityError function in nifgen

We need to deal with a range ('0-3' or '0:3'), a list ('0,1,2,3') and a single item
    '''
    # First we deal with a list
    rep_cap_list = repeated_capability.split(',')
    if len(rep_cap_list) > 1:
        # We have a list so call ourselves again to let the iterable instance handle it
        return _convert_repeated_capabilities(rep_cap_list, prefix)

    # Now we deal with ranges
    # We remove any prefix and change ':' to '-'
    r = repeated_capability.strip().replace(prefix, '').replace(':', '-')
    rc = r.split('-')
    if len(rc) > 1:
        if len(rc) > 2:
            raise errors.InvalidRepeatedCapabilityError("Multiple '-' or ':'", repeated_capability)
        start = int(rc[0])
        end = int(rc[1])
        if end < start:
            rng = range(start, end - 1, -1)
        else:
            rng = range(start, end + 1)
        return _convert_repeated_capabilities(rng, prefix)

    # If we made it here, it must be a simple item so we remove any prefix and return
    return [repeated_capability.replace(prefix, '').strip()]

Each instance should return a list of strings, without prefix
    - '0' --> ['0']
    - 0 --> ['0']
    - '0, 1' --> ['0', '1']
    - 'ScriptTrigger0, ScriptTrigger1' --> ['0', '1']
    - '0-1' --> ['0', '1']
    - '0:1' --> ['0', '1']
    - '0-1,4' --> ['0', '1', '4']
    - range(0, 2) --> ['0', '1']
    - slice(0, 2) --> ['0', '1']
    - (0, 1, 4) --> ['0', '1', '4']
    - ('0-1', 4) --> ['0', '1', '4']
    - (slice(0, 1), '2', [4, '5-6'], '7-9', '11:14', '16, 17') -->
        ['0', '2', '4', '5', '6', '7', '8', '9', '11', '12', '13', '14', '16', '17']
    '''
    raise errors.InvalidRepeatedCapabilityError('Invalid type', type(arg))
