Thanks A -- This is actually what I had coded prior to asking my question. The problem with this technique is the number of permutations! I have a rather sophisticated layout that contains a header, main and footer. Header contains four portions top, middle, bottom, crumbs and main has several sections. In order to mix/match (override) page definitions, I would need far too many tile-defs! If I could override, say, home.header.bottom from a sub definition this would be the cleanest. I would be interested in helping out with the Tiles coding if you think this is a possibility.
