How do I assign a character format in marker text?

[Lin23827968yzve]

I'm generating a List of Markers to serve as an index of figures with their respective sources rather than citing the source with each figure in the body of the book. I'm using a marker on each figure and then adding the source in the marker text. Some of the sources require bold or italicized type, and using the <> building blocks doesn't work; it just generates the text exactly as I type it into the Marker Text.

(So instead of  having "source stuff document title date" it says "source stuff <Italics>document title</> date")

I inherited this project and the syntax was already there, so I assume it was working in prior versions. What's wrong and how do I fix it?

Here is a 10-minute video that illustrates my programmatic solution. Apply character formatting to a list by making a FrameMaker index act like a FrameMaker list.
