The strings represent, in order:
1 - The builder name of the type linked to (i.e. people)
2 - The builder name of the relation (i.e. insrel) if an existing relation, otherwise the builder name of the typed linked to
3 - The number of the relation node if an existing relation, otehrwise the number of the current (edited) node
4 - Empty when an existing realtion. Otherwise it is either the name of the relation defintiton for a typed relation, or, when more than one relationtype exists for this node type, the value "multiple"
5 - GUI name for the node linked to. (empty when a relation type)
6 - "insEditor" if this is an existing node, "addeditor" if this is a rel;ation type.
7 - GUI name of the linked-to node's builder (language dependent)
8 - The gui name of the relation definition for this relation (appropriate for direction, empty when a relation type).

Parameters:
