Make the following changes with the standard for syntax as two words "value set" when referencing the concept - a set of codes or values - E.g., all of the uses shown in red should be two words: "Quality Measure and Clinical Decision Support authors and implementers should be cautious to prevent a reason for not performing a single item from a value set as indication that the reason applies to all valueset members. This may become more problematic as automated data extraction progresses and directly impacts EHR implementation. Clinicians require a rapid way to document that none of the members of the negation set could be selected. Caution is required to prevent a single member selection from being interpreted as if all valueset members were selected." However, if the term is used as part of a value set name or extension name, the one word approach is appropriate - 1.13.3 after the Note: "To report Antithrombotic Therapy Not Administered, implementing systems reference the canonical url of the “Antithrombotic Therapy” value set using the notDoneValueSetextension "
