Second question:
Are there currently any constraints on relations members based on:
1) Sequence
and/or
2) 'Reuse'
So would it be allowed to do:
type=node ref=1 role=from
type=node ref=2 role=at
type=node ref=1 role=at
type=node ref=3 role=to
Or is the second 1 not allowed?
Next to this; can a user explicitly trust the sequence 1,2,1,3; or is
this currently not guaranteed?
