title: How is the HL7 CDR component represented/implemented?
body: <p>I'm new to <code>HL7</code> and I'm trying to figure out how to represent the PID segment - namely PID-5-10.  PID-5-10 is the "CDR component" and it consists of 2 sub-components each made up of 2 values - <code>Time and Degree of Precision</code>. If I look at the standard separators defined in the MSH-2 it appears that there aren't enough separators to differentiate the <code>Time and Degree of Precision</code> values.</p>
  
  <p>e.g.</p>
  
  <pre><code>PID|1|2|3|4|5-1^^^^^^^^^5-10-1.Time?5-10-1.Precision&amp;5-10-2.Time?5-10-1.Precision^5.11
  </code></pre>
  
  <p>What's the standard separator I should use in place of the '?' in the above example?
  Any insight and assistance is much appreciated.</p>
