The ``<subject_increment>`` element defines a ``step`` to be added to the subject's current value when the ``trigger`` occurs.
Optionally, ``min`` and/or ``max`` can be set to limit the subject's value.
The ``<subject_increment_event>`` element defines a ``step`` to be added to the subject's current value
when the ``trigger`` occurs. Optionally, ``min`` and/or ``max`` can be set to limit the subject's value.
``subject`` must be an ``int`` or ``float`` subject.
If ``step`` is **negative**, the subject's value will be decremented.
Only integer ``step`` values are supported now.
**Note:** Only integer subjects are supported by ``<subject_increment>``.
