OPML question

I have seen OPML mentioned a few times (https://en.wikipedia.org/wiki/OPML) here and I have been requested to be able to support OPML import/export in Hyper Plan. But OPML seems to assume that the data is structured in a tree (node has max of 1 parent), whereas Hyper Plan connections are a graph (node can have >1 parent) and can even include cycles.

Out of interest, has anyone tried to get OPML to support graphs, rather than trees?

Surely some of the mind mapping tools use graphs? What do they do?
