-A reasonable assumption for this to understand is:

-At he moment, this is only listed here for information. There are a few potentially interesting aspects which might eventually be looked into:
+Another - simpler - way would be to directly link to a property which needs to be of type [[macros:type:boolean]]:
-  * this is, next to ''description'' and ''sequence'', another child of the ''macro'' element
-  * interesting syntax, with curly braces {} and propertyLink, converter, and converterParameter. Maybe we meet this again somewhere :-)

+In any case, **you can only bind to properties, not to functions**.
+  The active binding requires there to be a property, properties fire events
+  when they change which allow the UI to update. Generally the UI does not
+  continually call functions to get current values it depends on events to
+  allow it to update. (Gregory Haynes)
+//This is the reason why currently there is no way to use active binding to show whether a trigger mapping is enabled in [[macros:example:toggletriggermappings]] - there are no universal properties available for this as at compile time it is not known how many trigger mappings should be supported.//
+Active binding is referred to in these examples:
