Instance-specific? That sounds totally wrong to me, even given your own suggestion for the attribute's value (i.e., a URI). "Instance-specific" says to me, "true of this document instance," not "true of this element instance" -- the latter's what I meant when I said element-context-specific. In the latter case, a style sheet could *not* be used to establish behavior because there'd be no selector on the specific occurrence. It'd be like relegating href value assignment to a style sheet, no? The value to be used for a specific occurrence of that sort of behavior is not obtainable from the "meaning" of the tree structure at that point. Which value to use would be known to the author (human or otherwise), as a function of the "meaning" of that occurrence of that element, but unable to be communicated to a downstream application using other XLink (or style sheet selector) means.
