   Format: MarkdownItexadded a brief section _[Geometric and non-geometric backgrounds](http://ncatlab.org/nlab/show/type+II+geometry#GeometricAndNonGeometric)_ I thought I had once written a more detailed survey of this aspect somewhere already. But I can't find it right now. And maybe I just dreamed of having done so...
