• The XML element originalText may also be used to carry an XML element reference. This can be used to link the original text to the relevant text in the CDA section.

This template class constrains the CDA author class.

The author of the authority to LPA is the person who originally recorded the information of authority assigned to lasting power of attorney.

The author of this information must be included if the author and/or date of authoring are different to those for the document (inherited) author.

If there is no known author for the information held on the source system then:

• The information may be included and the document author will be deemed to the author (by inheritance). The author should be asked to decide whether this is acceptable or not.
• If the document author does not want to be considered as the author of the information then information must not be included in the document.
  

Model Attribute Description

Model Attribute Description

The HL7 attribute contextControlCode uses a set of codes from the HL7 vocabulary ContextControl to determine whether participations associated with the parent section are conducted across to the child section (also associated with the child section). This set of codes also determine how these participations conduct.

The conduction can only take place if the contextConductionInd in the actRelationships is set to "true".

The value of this attribute is fixed in the HL7 model to "OP":

• "O" (Overriding) - the author replaces any author that has been conducted from any previous acts.
• "P" (Propagating) - the author is conducted to all child acts where the contextConductionInd is set to "true".

Implementation in XML Instance

• The XML attribute contextControlCode shall contain the value "OP"

Model Attribute Description

The HL7 (NHS localisation) attribute contentId, when valued in an instance, provides a unique forward pointing identifier for the template which constrains the classes and attributes which follow, for NHS use.

The attribute is intended simply as a structural navigational aid and should not be relied upon as an indicator of semantic meaning. The contentId is populated at runtime with a value from the allowed list contained in the model.
