description	A globally unique string representing a DCE Universal Unique Identifier (UUID) in the common UUID format that consists of 5 hyphen-separated groups of hexadecimal digits having 8, 4, 4, 4, and 12 places respectively. ***NOTE:*** The output of UUID related programs and functions may use all sorts of forms, upper case, lower case, and with or without the hyphens that group the digits. This variate output must be postprocessed to conform to the HL7 specification, i.e., the hyphens must be inserted for the 8-4-4-4-12 grouping and all hexadecimal digits must be converted to upper case.	A globally unique string representing a DCE Universal Unique Identifier (UUID) in the common UUID format that consists of 5 hyphen-separated groups of hexadecimal digits having 8, 4, 4, 4, and 12 places respectively. ***NOTE:*** The output of UUID related programs and functions may use all sorts of forms, upper case, lower case, and with or without the hyphens that group the digits. This variate output must be postprocessed to conform to the HL7 specification, i.e., the hyphens must be inserted for the 8-4-4-4-12 grouping. Historically, CDA also required that all hexadecimal digits must be converted to upper case, but due to real-world issues encountered when enforcing this rule, it has been relaxed to allow for upper or lower case letters. Additionally, FHIR requires that UUID's be communicated using only lower case letters, so for broader compatibility, implementers are encouraged to use lower case letters.	Values Differ
