Hi,

this question is a good one, because it is a simple practical example for a
question of general importance. 

Like Dmitry said, there is only an official way in the BE (TCEmain). You
could instantiate it. but that is a lot of additional loading. Depending on
the circumstances, it can be a good solution. 

Steffen and Popy point to a simlar solution using specific cache flags.

Having a kind of slimTCE for the FE would sometimes be nice. 

@all: Could such a slim version be much faster the full BE TCE?
