It's basically a switch. In the current impl commands require '/' as a 
prefix and operations don't require anything. Here it's the opposite.

Operations performed at the current level (prefix address) would require 
':'.
Operations performed at a deeper level than the current one (if they 
need to specify additional address part) would start with './' then the 
address part, then ':' + operation name.
Or, if you want to start from the root node, you'll have to start with '/'.

Commands won't require any prefix.
