Hi Sune, Thanks for getting this thread going. Your outline is pretty close to the way I've been doing things too.
Seeing it in writing got me wondering though if the whole idea of application templates "extending" the base site is wrong-headed. Because the application knows nothing about the site it is to be embedded in, the application writer is second-guessing what base template it is supposed to extend. Say the 'blog' and 'gallery' applications need to appear on the same page in different columns...what then? Shouldn't we encourage a model where site templates are able to explicitly "include" application templates, rather than the other way around? Though I haven't used it, the 'ssi' tag looks like the kind of thing I have in mind. Kieran
