With the current formatter it is only possible to use rules based on the
grammar. You need to write your own formatter.
I am however working on a semantic formatter with the intent of donating
it to Xtext. It is not quite finished yet, but for the brave, and those
that want to make sure their formatting needs are supported, it is
possible to experiment with it right now.
My plan was to invite others to try it and provide feedback in a week or
two - but if someone really wants to I am happy to help with information
how to use it.
It is in cloudsmith/geppetto @ github if you want to go on a hunt on
your own.
