I ran into this when I tried to write a loader for ODE. It is doable to save 
all objects and joints and there relations to a file given just a dWorldID. 
Something like:
void dWorldSave(dWorldID world, const char *filename);
But then you won't have the geoms. You could save geoms that are attached to 
bodies, because the bodies have pointers to those geoms. But that way you 
won't get the static geoms. So if you would want to save the whole simulation 
then you would have to come up with a more complex function I think.
But if you are using wrapper classes for ODE then this method of saving is 
pretty much useless, because you would only have the lowlevel ODE stuff and 
not the wrapper objects themselves. So you would probably end up writing your 
own loader/saver.

It could be usefull to define a number of XML tags and their relationships, so 
you could use those tags in your own XML format (if you would choose XML).
