Which parameter should be used for tag volume?

[benjamindehli]

Both AMP_VOLUME and TAG_VOLUME seem to work as parameter value when using a binding with type="amp" level="tag".

Is one of them preffered over the other?

<binding type="amp" level="tag" identifier="16" parameter="AMP_VOLUME" translation="linear" translationOutputMin="0" translationOutputMax="1" />
<binding type="amp" level="tag" identifier="16" parameter="TAG_VOLUME" translation="linear" translationOutputMin="0" translationOutputMax="1" />
