%% It is important to end with a call to xserl:built_in_rules/2
%% if you want any text to be written in "push" transforms.
%% That are the ones using a lot xslapply( fun template/1, E )
%% instead of value_of(select("xpath",E)), which is pull...
%% Could maybe be caught as an exception in xslapply instead,
%% but I think that could degrade performance - having an
%% exception for every #xmlText element.
