Me again (last one for tonight!)

Aquisition is groovy, but is it possible to refine aquired properties instead of redefining them from scratch?

(Creating a standard_html_header in s subfolder and using <dtml-var standard_html_header> does not produce expected result, that is grabbing the upper-level's definition of standard_html_header).

Is there a DTML tag such as <dtml-refine> which, when stated at a given level, would indicate where to insert sublevel redefinition of the DTML method?

Maybe i'm thinking too much of OO inheritance...

You know, I've never really gotten this either. Maybe Jim Fulton could explain for us one more time or else point us at a good explanation of -why- acquisition begins at the root and goes down the tree instead of starting at the current level and going up, which I believe is what pretty much everyone expects it to do when they first run across it.

The slides from Jim Fulton's "Acquisition Algebra" talk are online: http://www.zope.org/Members/jim/Info/IPC8/AcquisitionAlgebra/index.html I know the title is intimidating, but I think the talk was "satori-making".
