0. Observation
Definition	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. Base definition for all types defined in FHIR type system.
Short	Base for all types and resources
Control	10..1*
Is Modifier	false
Logical Container	ClinicalDocument (CDA Class)
Validation	Instance of this type are validated by templateId
XML Format	In the XML format, this property has the namespace `urn:hl7-org:v3`.
2. Observation.nullFlavor
Definition	If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.
Control	0..1
Binding	The codes SHALL be taken from CDANullFlavor (required to `http://hl7.org/cda/stds/core/ValueSet/CDANullFlavor`)

Short	links to the rendering of Healthcare Agent powersText summary of the resource, for human interpretation
Comments	Contained resources do not have a narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied).

Definition	The patient, or group of patients, location, device, organization, procedure or practitioner this observation is about and into whose or what record the observation is placed. If the actual focus of the observation is different from the subject (or a sample of, part, or region of the subject), the `focus` element or the `code` itself specifies the actual focus of the observation.
Short	Who and/or what the observation is about
Comments	One would expect this element to be a cardinality of 1..1. The only circumstance in which the subject can be missing is when the observation is made by a device that does not know the patient. In this case, the observation SHALL be matched to a patient through some context/channel matching technique, and at this point, the observation should be updated. The subject of an Observation may in some cases be a procedure. This supports the regulatory inspection use case where observations are captured during inspections of a procedure that is being performed (independent of any particular patient or whether patient related at all).

Definition	The specimen that was used when this observation was made.
Short	Specimen used for this observation
Comments	Should only be used if not implicit in code found in `Observation.code`. Observations are not made on specimens themselves; they are made on a subject, but in many cases by the means of a specimen. Note that although specimens are often involved, they are not always tracked and reported explicitly. Also note that observation resources may be used in contexts that track the specimen explicitly (e.g. Diagnostic Report).

XML Format	In the XML format, this property has the namespace `urn:hl7-org:sdtc`.In the XML format, this property has the actual name`precondition2`.
96. Observation.referenceRange
Definition	Relates an Observation to the ObservationRange class, where the expected range of values for a particular observation can be specified. Guidance on how to interpret the value by comparison to a normal or recommended range. Multiple reference ranges are interpreted as an "OR". In other words, to represent two distinct target populations, two `referenceRange` elements would be used.
Short	Provides guide for interpretation
Comments	Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate. Whenever more than one reference range is supplied, the differences between them SHOULD be provided in the reference range and/or age properties.
