+/**
+ * A dispatcher that serves as a proxy for style commands with arguments
+ * i.e. .uno:StyleApply?... in order to provide useful status updates to
+ * generic UI elements such as toolbars or menubar. It listens to special
+ * status commands, and computes a boolean status out of them. Then it
+ * forwards that boolean status to the listener, as if it was the status
+ * of the original command.
+ *
+ * Note that the implementation is minimal: Although the UI element appears
+ * to be the owner of the dispatcher, it's still responsible, as usual, to
+ * call removeStatusListener same amount of times as addStatusListener,
+ * otherwise the dispatcher might not be destructed. In addition this
+ * implementation might hold a hard reference on the owner, and it's the
+ * responsibility of the owner to destroy the dispatcher first, in order
+ * to break the cycle.
