[TYPO3] Is template switching on the fly possible?

You first have to know whether you use TemplaVoilà or not. If yes, you 
may create alternate layouts within the definition of templates in 
TemplaVoilà. This is multiple TO with the same DS and an additional 
configuration option. You have to use "make this a subtemplate of" and 
choose your master template. Then you may choose a type of rendering (in 
the documentation it is explained how to create new types). I created 
one that is "Atom Feed" and that corresponds to type=100:

vs

If you choose not to use TemplaVoilà, then you may easily load another 
template file with a condition, see
