Document sections can nest, can override context propagated from the header (See CDA Context), and can contain narrative and CDA entries.
An XML attribute "ID" of type XML ID, is added to Section within the CDA Schema. This attribute serves as the target of a linkHtml reference (see linkHtml). All values of attributes of type XML ID must be unique within the document (per the W3C XML specification).
