Very much like this can be done with the <obs/> tag when using radio buttons to pick its answers, the <condition/> tag could be preset to point to a specific condition for which the clinical status' value ('active', 'inactive', 'history of') remains the only choice to make.
When doing this:
then the condition search box would be either disabled or somehow inactive and the condition would be preset to be that defined by CIEL:1234.
Failing to select the clinical status will result in the preset condition to not be submitted.
Failing to select the clinical status will not result in a validation error since the condition is not submitted.
