  <description
               value="This ValueSet is part of the Health Device Data Transfer specification (HDDT) which defines profiles, operations, and value sets 
for sharing data between medical aids and digital health applications (DiGA). 

This ValueSet defines the LOINC codes, used for relative lung function values. The relative value is calculated by dividing the 
individual measurement by the reference value, resulting in a percentage value (%). Included codes are for 
- FEV1 measured/predicted
- PEF measured/personal best"/>
