okay, thanks for the clarification. In this case it would be great if 
the "|"  could be used for display_name, ref, int_ref, nat_ref too! (or 
maybe even better for all add / set actions ) and additionally a command 
to append  would be great too.
At least that clarification makes it a lot easier for route names now 
for me. Instead of having the line

set route_name='${name}'; set ref='${ref}'

I will now simply use

set int_ref='${name};${ref}|highway-symbol:hbox:6:4}'

And will not be forced to fiddle around with how I append route_name to 
name in the general style-file.

As last question - what happens if there are more than 4 labels - are 
label 5 and onwards simply dropped?
