  div: Generated Narrative: ValueSet CDACompressionAlgorithm Include these codes as defined in http://terminology.hl7.org/CodeSystem/v3-CompressionAlgorithm version ?2.1.1 Code Display Definition DF deflate The deflate compressed data format as specified in RFC 1951 \[http://www.ietf.org/rfc/rfc1951.txt\]. GZ gzip A compressed data format that is compatible with the widely used GZIP utility as specified in RFC 1952 \[http://www.ietf.org/rfc/rfc1952.txt\] (uses the deflate algorithm). ZL zlib A compressed data format that also uses the deflate algorithm. Specified as RFC 1950 \[http://www.ietf.org/rfc/rfc1952.txt\] Z compress Original UNIX compress algorithm and file format using the LZC algorithm (a variant of LZW). Patent encumbered and less efficient than deflate.
