The Comment Observation template is a generic comment template that may be referenced
from different sections or entry templates to support the consistent communication
of a comment. Comments are free text data that cannot otherwise be recorded using
data elements already defined by this specification. They SHALL NOT be used to record information that can be recorded elsewhere. For example, a free
text description of the severity of an allergic reaction SHALL NOT be recorded in a comment but SHALL be communicated through the applicable data element.
