This entry allows for a comment to be supplied with each entry. For CDA this structure
is usually included in the target act using the <entryRelationship> element defined
in the CDA Schema, but can also be used in the <component> element when the comment
appears within an <organizer>. The example below shows recording a comment for an
<entry>, and is used as context for the following sections. For HL7 Version 3 Messages,
this relationship is represented with the element <sourceOf>, although the remainder
of the typecodes and
semantics are unchanged.
Any condition or allergy may be the subject of a comment.
