That's good stuff.

The tool should have a 'generate on edit' knob on the representation 
chains, so common chains can be pre-generated at the point of editing, 
if so required.

Examples where this may be desirable are: process-intensive 
transformations which may block the rendering of the representation, 
such as a PDF output; or spell-checking where you pass the text through 
aspell or similar.
