The difference here is that there are no predefined limits to the
number of various connections. Even if I was able to sort out the
simplest scenario (two bodies connected by one joint) I think that I
would run into issue with the actual formatting of the page, where to
locate the diagrams, intersecting lines etc...

this sounds promising to hear.

Yes, I'm sorry in an effort of simplifying the XML file I made a mistake.
I meant exactly what you wrote above.

If you could share anything that applies, that would be *much* appreciated!
