### 10.5.1 text/reference and Related Narrative Block Markup

The Observation entry SHOULD include a text/reference element, whose value attribute (not to be confused with the value element of the Observation class) SHALL begin with a '#' and SHALL point to its corresponding narrative in the parent section (using the approach defined in CDA Release 2, section 4.3.5.1). See Section 9.1.1.1.
