Microsoft is not exactly clear what this means, but it seems likely it refers to
the ability to bind a range of a constant buffer [i.e. with
ID3D11DeviceContext::*SetConstantBuffers1()] rather than the whole buffer.

Relevant portion of the D3D11 spec:

Ah, so it's about performing partial updates of constant buffers via 
UpdateSubresource(), which apparently is forbidden in 11.0. Well, we 
support that too, so the patch is still correct, although the commit 
message is not :-)
