[themes] proposal for theming nodes

[Bèr Kessels]

Hi,

way too often i have to hack modules or even core (upload) to make it *not* 
append HTML to $node->body.

I think this practice of appending stuff to the body is very bad, since it 
makes it impossible to add thatdata elsewhere, without duplication.

I think that teh best option is an additional variable in $node
$node->extra 
containing structured data added by all the modules. 
$node->extra->upload could, for example contain that uplaod/attachement table, 
that is now hardcoded to the body.

In the very very end, the theme_node will iterate over all these ->extra 's 
and append them to teh body.

Now, the code, the patch, should not be too hard to make, its just a few lines 
to the theme_node functions

The hard part, imho is to convert **all** core modules to use this. and with 
All i mean all :). Taxononomy, for example, should add its terms in there, 
while book module should add its navigation. 

The other thing is, that while this annoys me a huge lot, i just don't have 
time to get a patch going, untill at least end of Januari. 

Waht do others think

PS: Im not to sure about tis crossposting thing, but there are loads of theme 
and developers issues; is it safe to assume that interested parties at least 
read development? (so that we can keep this on development)
