/**
* A BindingConfig object targeted at MiOS Scene Attributes.
*
* The scene-specific form of a MiOS Binding is:<br>
* <ul>
* <li><nobr> <tt>mios="unit:<i>unitName</i>,scene:<i>sceneId</i>/<i>attrName</i>,<i>optionalTransformations</i></tt>
* </nobr>
* </ul>
* <p>
*
* Example Item declarations:
* <p>
* <p>
* <ul>
* <li>
* <code><nobr>String SceneAlarmArrivingDisarmed "Alarm Arriving Disarmed Scene" <sofa> (GScene) {mios="unit:house,scene:2/status,command:,in:MAP(miosStatusIn.map)", autoupdate="false"}</nobr></code>
* <li>
* <code><nobr>Contact SceneAlarmArrivingDisarmedActive "Active [%s]" <sofa> {mios="unit:house,scene:2/active,in:MAP(miosSceneActiveIn.map)"}</nobr></code>
* </ul>
* <p>
*
* <b>Optional Transformations</b>
* <p>
* See the Optional Transformations section of the JavaDoc for {@link DeviceBindingConfig} for a description of the main
* options here.
*
* The one addition is that Scene Bindings also support:
* <ul>
* <li><code>command:</code> - map <i>any</i> openHAB Command sent to the Item, and use it to trigger Scene execution.
* <li><code>command:ON</code> - map <i>only</i> the <code>ON</code> Command sent to the Item, and use it to trigger
* Scene execution ("<code>ON</code>" can be any openHAB Command string)
* </ul>
