       by enableBehavior (either all repetitions must evaluate to true for this item to
       be enabled, or only one must evaluate to true for the item to be enabled).  If
       the enableWhen.question has multiple answers, the condition evaluates to true if
       *any* of the answers for the referenced item match the enableWhen condition.  This
       element is a modifier because if enableWhen is present for an item, &quot;required&quot;
       is ignored unless one of the enableWhen conditions is met. When an item is disabled,
       all of its descendants are disabled, regardless of what their own enableWhen logic
       might evaluate to.  If enableWhen logic depends on an item that is disabled, the
       logic should proceed as though the item is not valued - even if a default value
       or other value might be retained in memory in the event of the item being re-enabled.
        In some cases, the comparison between the indicated answer and the specified value
       may differ only by precision.  For example, the enableWhen might be Q1 &gt; 1970,
       but the answer to Q1 is 1970-10-15.  There is not a clear answer as to whether
       1970-10-15 should be considered 'greater' than 1970, given that it is an imprecise
       value.  In these indeterminate situations, the form filler has the option of refusing
       to render the form.  If the form **is** displayed, items where enableWhen is indeterminate
       SHOULD be treated as enabled with a warning indicating that the questionnaire logic
       was faulty and it is possible that the item should not be enabled.  Questionnaires
       SHOULD be designed to take into account challenges around varying precision to
       minimize non-deterministic situations by setting constraints around expected precision,

       by enableBehavior (either all repetitions must evaluate to true for this item to
       be enabled, or only one must evaluate to true for the item to be enabled).  If
       the enableWhen.question has multiple answers, the condition evaluates to true if
       *any* of the answers for the referenced item match the enableWhen condition.  This
       element is a modifier because if enableWhen is present for an item, &quot;required&quot;
       is ignored unless one of the enableWhen conditions is met. When an item is disabled,
       all of its descendants are disabled, regardless of what their own enableWhen logic
       might evaluate to.  If enableWhen logic depends on an item that is disabled, the
       logic should proceed as though the item is not valued - even if a default value
       or other value might be retained in memory in the event of the item being re-enabled.
        In some cases, the comparison between the indicated answer and the specified value
       may differ only by precision.  For example, the enableWhen might be Q1 &gt; 1970,
       but the answer to Q1 is 1970-10-15.  There is not a clear answer as to whether
       1970-10-15 should be considered 'greater' than 1970, given that it is an imprecise
       value.  In these indeterminate situations, the form filler has the option of refusing
       to render the form.  If the form **is** displayed, items where enableWhen is indeterminate
       SHOULD be treated as enabled with a warning indicating that the questionnaire logic
       was faulty and it is possible that the item should not be enabled.  Questionnaires
       SHOULD be designed to take into account challenges around varying precision to
