RFC 5153, "IP Flow Information Export (IPFIX) Implementation Guidelines", April 2008

Section 7.2 says:

   Consequently, an Exporting Process reporting traffic Flows measured   at a device that hosts one or more middleboxes should clearly   indicate to Collecting Processes the location of the used Observation   Point(s) with respect to the middlebox(es).  This can be done by   using Options with Observation Point as scope and elements like, for   instance, lineCardID or samplerID.  Otherwise, processing the   measured Flow data could lead to wrong results.

It should say:

Section 3.3 says:

   Note that it is sometimes necessary to export information about   entities that exist outside any Observation Domain, or within   multiple Observation Domains (e.g., information about Metering   Processes scoped to meteringProcessID).  Such information SHOULD be   exported in an IPFIX Message with Observation Domain ID 0 (see   [RFC5101], Section 3.1).

Notes:

s/meteringProcessID/meteringProcessId/

Per RFC5102 and IANA's IPFIX registry, the correct name is "meteringProcessId".
