Could you give an example of how to do it?

I do understand the reqgexp not well enough, to split up values into to 
keys! I didn't know this was possible - so I'ld like to try it out.
If it's possible, then yes of course, this should go into the default 
style. My change wish, was based on the knowledge that this is not 
possible (about 2 years ago it certainly was not).
