A derivative of the RIM Observation class, used for representing coded and other observations. Observation.negationInd, when set to "true", is a positive assertion that the Observation as a whole is negated. Some properties such as Observation.id, Observation.moodCode, and the participations are not negated. These properties always have the same meaning: i.e., the author remains the author of the negative Observation. An observation statement with negationInd is still a statement about the specific fact described by the Observation. For instance, a negated "finding of wheezing on July 1" means that the author positively denies that there was wheezing on July 1, and that he takes the same responsibility for such statement and the same requirement to have evidence for such statement than if he had not used negation.
HL7 International - Structured Documents
Defines the basic properties of every data value. This is an abstract type, meaning that no value can be just a data value without belonging to any concrete type. Every concrete type is a specialization of this general abstract DataValue type.
If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.
When valued in an instance, this attribute signals the imposition of realm-specific constraints. The value of this attribute identifies the realm in question
When valued in an instance, this attribute signals the imposition of constraints defined in an HL7-specified message type. This might be a common type (also known as CMET in the messaging communication environment), or content included within a wrapper. The value of this attribute provides a unique identifier for the type in question.
An II instance must have either a root or an nullFlavor.
A human readable name or mnemonic for the assigning authority. The Assigning Authority Name has no computational value. The purpose of a Assigning Authority Name is to assist an unaided human interpreter of an II value to interpret the authority. Note: no automated processing must depend on the assigning authority name to be present in any form.
Specifies if the identifier is intended for human display and data entry (displayable = true) as opposed to pure machine interoperation (displayable = false).
Identifies the type as an HL7 Registered model
A character string as a unique identifier within the scope of the identifier root.
When valued in an instance, this attribute signals the imposition of a set of template-defined constraints. The value of this attribute provides a unique identifier for the templates in question
Relates an Observation to the ObservationRange class, where the expected range of values for a particular observation can be specified.
