(Or alternatively, the input could be a concatenation of documents on which the CSS has already been applied before the merge; should come down to the same thing.)
The first consequence I can think of is that if a different @volume rule is applied to different documents, all except the first rule will be (silently) ignored. We currently can not handle this correctly because in OBFL volume-template is not part of layout-master (see https://github.com/braillespecs/obfl/issues/34). Note that this is also the reason why we can't implement the volume property.
I'm not sure whether there are other consequences I didn't think of yet.
