<!--
Naming rules
- functions eg: tf.toc-variableName, "tf." ... function prefix reservered for TW, "toc-" ... global macro prefix, "variableName"
- procedures eg: toc-procedureName,
- macro parameters: path, itemTemplate
- derived macro parameters: _path, _itemTemplate ... derived variables start with an underscore
- some \function definitions are near their first use in the middle of the code, to find them easily

The toc-macro code is heavily reused from top to bottom.
toc-tabbed-internal-nav calls toc-tabbed-external-nav, which calls toc-selective-expandable, which calls toc-expandable

The very first toc macro is _not_ reused. So it can be used as a simple reference implementation, because it is relatively easy to debug.
