No, you got it right. It looks like this is a problem in the
documentation -- it appears that, like you said, EdgeListGraph is
required.

That would still require IncidenceGraph, which is also not mentioned in
the documentation. Would it be hard for you to model EdgeListGraph? Do
you have memory space to just make an std::vector of your edges? That
would make the model trivial to write.
Could you please file a bug at svn.boost.org about the documentation
issue? It is a definite problem.
