I am doing a tutorial found on the Side FX site, and in this tutorial is 
used the following expression to define the red component of a color :

tex("op://obj/grid_object1/cop2net1/ramp1", $BBX, $BBZ, r)

Where in the doc can I find why the op: is needed ?

I found, in the "Use compositor images in other nodes", a mention to 
that, but I don't know if it's specific to this case, or if this "op:" 
use follows a more general rule.
