Notes:
This records the Weight of the PERSON.

This corresponds to MEASURED OBSERVATION VALUE where the MEASURED PERSON OBSERVATION TYPE CODE = 'Weight' and the MEASUREMENT VALUE TYPE CODE = 'Kilograms'.

The field must be padded to match the Format/Length pattern of n3.n3, for example 001.100 is a valid entry (1.1 is invalid).

For neonatal critical care, this will be the last recorded Weight on a particular ACTIVITY DATE (CRITICAL CARE).
