Hi Ryan,
as far as I understand it the TOC is only looking for "Headings" (but maybe I don't understand the settings correctly..)
I would like to see it looking for other tags or classes or definitions, e.g. search for all or for definitions in a text, like
Lorem ipsum dolor sit amet, <toc_marker>consectetuer</toc_marker> adipiscing elit. Morbi congue velit ac nisl. Pellentesque viverra volutpat sem. Cras lobortis, massa et adipiscing sollicitudin, pede dui tempo.
lorem, at <toc_marker>scelerisque </toc_marker>massa nunc vitae magna. Etiam laoreet. Aliquam volutpat, ipsum eget accumsan egestas, mi eros euismod tortor, sit amet vulputate leo orc.i
