A Nodepath is a way of defining the levels in an Aggregation.

For example, an Aggregation with the following levels:
Level 1: Visibility Point (root node)
Level 2: External Group name (branch node)
Level 3: Switchport (branch node)
Level 4: Market Data feed (branch node)
Level 5: Market Data feed Side - A or B (branch node)
Level 6: Market Data feed Channel (leaf node)

may have the nodepath vp/extgroup/switchport/feed/side/channel, which indicates the levels and hierarchy in the Aggregation from root to leaf, or might have partial nodepaths that represent the levels from root to branch, such as vp/extgroup/switchport/.
