To answer the subject question, a ModelTreeNode category is a
category associated with a given ModelTreeNode. It's presently
used to permit the grouping of sets of related items in the
Outline view.

The issue here is that what gets handed to a LabelProvider is
*not* a ModelTreeNode, but rather the AST that the ModelTreeNode
represents.

I think that you might be able to achieve the effect you want
if you could (optionally) use a different LabelProvider just for
the Outline view, and that LabelProvider could supply the prefix
as well as the rest of the label in your example.

This augmented LabelProvider could always instantiate the "normal"
LabelProvider implementation, and add to whatever it produces.

Does that sound like it addresses your need?
