Hello,
Using process book to add symbols to an AF element's template shows that extended properties can hold xml information. When viewed in the Pi System Explorer, the Name and Value of the extended property can be edited.
The Value type for xml is Basic Types -> String, and as shown in the attached image, can be edited by the "Text Visualiser" by clicking on the [...] icon.
However, when i have created my own custom xml as an extended property of type Basic Types -> String, the "Text Visualiser" is not available to edit it.
How can i make the text visualiser available for use with my own custom xml strings in extended properties?
