When hooking up routes, use a 2-pass search:
1. exact match
if didn't find then
2. synonym match ie set_, _changed

> which is aliased to the corresponding 'children' x3d field. A
> 'level_changed' event therefore is then treated as output from the
> MFNode 'children' field, and not as output from the SFInt
> 'level_changed' field.
> A possible fix is to only do the aliasing if we know the original
> encoding of the LOD node was vrml. This fix may be ok if the LOD node
> is the only node which could have this conflict stemming from renaming
> a vrml field ('level' to 'children') and at the same time introducing
> a new x3d field ('level_changed') with the old vrml name of the
> renamed field.
> So my question is if there may be other nodes with fields which were
> affected by renaming from vrml to x3d in such a way ?
> If there are a few others it may be worth looking for a solution which
> does not need special treatment of certain nodes.
