      In Medication Activity, CONF:1098-7508 and its sub-entries describe time as either a single point in time or a period:

      If a medication was administered once, the time would be represented as:
      <effectiveTime value="DATETIME"/> //Using effectiveTime/@value to represent a single medication administration time

      If the medication was administered over a period of time:
      <effectiveTime>
      <low value="DATETIME"/> //Period start
      <high value="DATETIME"/> //Period end
      </effectiveTime>

      For Medication Order, CONF:4388-27740 and its sub-entries describe only a period of time:
      <effectiveTime>
      <low value="DATETIME"/> //Period start
      <high value="DATETIME"/> //Period end
      </effectiveTime>

      When Medication Order is negated, a nullFlavor can be used in the required effectiveTime elements.

      We are currently using Hl7 Guide Release 5.1 Errata for QRDA1 Export analysis for ambulatory system. Page #224, #297 mentions effectiveTime with @value attribute. Value attribute definition is mentioned as "indicates a single-administration timestamp".

      1) What exactly it means when it comes to Medication order and Active templates?

      2) What should be the <effectiveTime> tag low, high or @value attribute for "medication not ordered" template? Per guide, its medication start and end date or single administration. But since this is negation template, there wont be any medication start, end or single administration date. Hence what should we print here?
