Section 4.5.3 says:
In the exceptional case of zero instances in the subTemplateMultiList, no data is encoded, only the Semantic field and Template ID field(s), and the Data Record Length field is set to zero.
It should say:
In the exceptional case of zero instances in the subTemplateMultiList, no data is encoded, only the Semantic field and Template ID field(s), and the Data Records Length field is set to four.
Notes:
s/zero/four/ && s/Record/Records/
- because the Data Record Length field includes two bytes for the Template ID and two bytes for the Data Records Length field itself, as specified on page 23:
Data Records Length
This is the total length of the Data Records encoding for the
Template ID previously specified, including the two bytes for the
Template ID and the two bytes for the Data Records Length field
itself.
Therefore, a Data Records Length < 4 bytes is invalid. This should be noted in the "Data Records Length" definition.
Also note the pluralisation of "Records" in the definition.

Notes:
s/observationTimeMicroSec/observationTimeMicrosec/
Per RFC5477 and IANA's IPFIX registry, the correct name is "observationTimeMicroseconds".

A new IPFIX registry has been created, and the existing IPFIX Information Element registry has been updated as detailed below.
Notes:
Only one new registry has been created - for the "structured data types semantics", per section 11.4 of the document.

"Reducing Redundancy in IP Flow Information Export (IPFIX) and Packet Sampling (PSAMP) Reports" [RFC5473] describes a bandwidth saving method for exporting Flow or packet information using the IP Flow Information Export (IPFIX) protocol.

Notes:
s/defines/discusses/
- commonPropertiesId is not defined in [RFC5473], but in [RFC5101].
[RFC5473] doesn't have any IANA actions.

Notes:
s/octetCount/octetTotalCount/ (twice)
s/packetCount/packetTotalCount/ (twice)
"octetCount" and "packetCount" don't exist. Per RFC5102 and IANA's IPFIX registry, the correct names are octetTotalCount and packetTotalCount.
NB correct usage in the figure on page 43 and in Figure 20 indicates that these are not the DeltaCount form.
