As discussed we probably won't need this variant, we can probably drop it and
add it later if really necessary.

Done.

Does this need to be public?

[alancutter (OOO until 2018), 2013/07/30 08:31:02]

We don't really need it at this stage, it can be exposed later if needed. For
now I removed it from the header file.
