Duplicate array element IDs add new IDs

[finkn]

When element IDs collide, depending on the order in which the parameters occur in the configuration, elements may have an ID that is relative to a different parent ID.

For example, the first element of the array "A.1" can be assigned an ID of "A.A.1.1".
