However, the list does specifically include "Springer": see i.e.  Springer Bibliography Requirements

What is a similar Refworks output style choice/item, which is similar to the Springer requirements?
The "Springer" document that you linked contains specific instructions for how to contribute to Springer Computer Science Proceedings. It also says:


  You will find here Springer’s guidelines for the preparation of
  proceedings papers to be published in one of the following series, in
  printed and electronic form


That means that those instructions are valid for all the journals and publications listed below.

So try to look for one of those style (i.e.: Lecture Notes in Computer Science) and it should work.
