I think that a comma is missing there [1]: Because of these possible side effects, applications must select an output before querying or negotiating any other parameters. IMO, reverting the order of the explanation clause is semantically better, as it bolds the need to select an output, and put the phrase at the cause-effect order: Applications must select an output before querying or negotiating any other parameters, because of these possible side effects. But this is really a matter of choice. In any case, except for the comma, that makes sense for me.
