    <div xmlns="http://www.w3.org/1999/xhtml">
      <p>The ClinicalDocument class is the entry point into the CDA R-MIM, and corresponds to the &lt;ClinicalDocument&gt; XML element that is the root element of a CDA document.</p>
      <p>A CDA document is logically broken up into a CDA Header and a CDA Body. The CDA Header is comprised of ClinicalDocument attributes, participants, and act relationships. The CDA Body is the target of the ClinicalDocument component act relationship.</p>
      <p>The ClinicalDocument class inherits various attributes from the InfrastructureRoot class of the RIM, including ClinicalDocument.templateId and ClinicalDocument.typeId. When ClinicalDocument.templateId is valued in an instance, it signals the imposition of a set of template-defined constraints. In addition, the templateId attribute is available in all other CDA classes, thus enabling the imposition of a set of template-defined constraints at any level of granularity. The value of this attribute provides a unique identifier for the template(s) in question.</p>
      <p>ClinicalDocument.typeId is a technology-neutral explicit reference to this CDA, Release Two specification, and must be valued as follows: ClinicalDocument.typeId.root = &quot;2.16.840.1.113883.1.3&quot; (which is the OID for HL7 Registered models); ClinicalDocument.typeId.extension = &quot;POCD_HD000040&quot; (which is the unique identifier for the CDA, Release Two Hierarchical Description).</p>
