Hi, Firstly let me commend you on the quality of your plugin, for a non-commercial plugin it is one of the best, most comprehensive plugs I have ever used.
I have a small query relating to Wikitude ARML output that it would be great if you could answer. I have noticed than when a marker description is parsed to ARML any html is removed, and so links cannot be embedded into the marker descriptions. It looked like in the code that you had begun to implement use of the wikitude:url property, but it is commented out. Do you plan to implement the addition of wikitude:url and wikitude:attachment properties in new versions of the plugin, perhaps as additional properties that are defined alongside the marker description. I think this would be a great addition to the code, and am happy to assist where I can.
Many thanks again,
