  -The two styles are not interchangeable. For example, it is not valid to use `node[Routers:atledg04]` nor to use `nodeSource[175]`.

  -IMPORTANT: On systems where `storeByForeignSource` is enabled, you must *always* use the `nodeSource` style when referring to requisitioned nodes and `node` when referring to auto-provisioned nodes. The following tables summarize which style is permissible in which situation. Auto-provisioned nodes are ones that do not belong to any requisition. As these nodes lack a foreign-source name, they intrinsically cannot be represented using `nodeSource` style identifiers.

  The node identifier is followed by a period, then a resource-type name and instance name. The instance name's characteristics may vary from one resource-type to the next. A few examples:

  | `nodeSnmp[]`                       | Node-level (scalar) performance data for the node in question. This type is the only one where the instance identifier is empty.
  | `interfaceSnmp[eth0-04013f75f101]` | A layer-two interface as represented by a row in the SNMP `ifTable`. The instance identifier is composed of the interface's `ifName` and its `ifPhysAddress` (if it has one).
  | `dskIndex[_root_fs]`               | The root filesystem of a node running the Net-SNMP management agent.

  === Identifying Resources
  
  Some endpoints deal in resources, which are identified by _Resource IDs_.
  Since every resource is ultimately parented under some node, identifying the node which contains a resource is the first step in constructing a resource ID.
  Two styles are available for identifying the node in a resource ID:
  
  [options="header", cols="5,10,10"]
