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.

If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.

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).

Specifies if the identifier is intended for human display and data entry (displayable = true) as opposed to pure machine interoperation (displayable = false).

A unique identifier that guarantees the global uniqueness of the instance identifier. The root alone may be the entire instance identifier.

SHALL contain exactly one [1..1] @classCode="SPLY" (CodeSystem: HL7ActClass urn:oid:2.16.840.1.113883.5.6 STATIC) (CONF:1098-8745).

If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.

Indicates whether the raw byte data is compressed, and what compression algorithm was used.

The integrity check is a short binary value representing a cryptographically strong checksum that is calculated over the binary data. The purpose of this property, when communicated with a reference is for anyone to validate later whether the reference still resolved to the same data that the reference resolved to when the encapsulated data value with reference was created.

Specifies the algorithm used to compute the integrityCheck value. The cryptographically strong checksum algorithm Secure Hash Algorithm-1 (SHA-1) is currently the industry standard. It has superseded the MD5 algorithm only a couple of years ago, when certain flaws in the security of MD5 were discovered. Currently the SHA-1 hash algorithm is the default choice for the integrity check algorithm. Note that SHA-256 is also entering widespread usage.

For character based information the language property specifies the human language of the text.

Identifies the type of the encapsulated data and identifies a method to interpret or render the data.

Data that is primarily intended for human interpretation or for further machine processing is outside the scope of HL7. This includes unformatted or formatted written language, multimedia data, or structured information as defined by a different standard (e.g., XML-signatures.)

This element is represented in XML as textual content. The actual name "xmlText" will not appear in a CDA instance.

A telecommunication address (TEL), such as a URL for HTTP or FTP, which will resolve to precisely the same binary data that could as well have been provided as inline data.

An abbreviated rendition of the full data. A thumbnail requires significantly fewer resources than the full data, while still maintaining some distinctive similarity with the full data. A thumbnail is typically used with by-reference encapsulated data. It allows a user to select data more efficiently before actually downloading through the reference.

SHALL contain exactly one [1..1] statusCode (CONF:1098-8749).

If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.

The plain code symbol defined by the code system. For example, "784.0" is the code symbol of the ICD-9 code "784.0" for headache.

Specifies the code system that defines the code.

The common name of the coding system.

If applicable, a version descriptor defined specifically for the given code system.

A quantity specifying a point on the axis of natural time. A point in time is most often represented as a calendar expression.

A code specifying whether the set component is included (union) or excluded (set-difference) from the set, or other set operations with the current set component and the set as constructed from the representation stream up to the current point.

This is the low limit of the interval.

The arithmetic mean of the interval (low plus high divided by 2). The purpose of distinguishing the center as a semantic property is for conversions of intervals from and to point values.

The difference between high and low boundary. The purpose of distinguishing a width property is to handle all cases of incomplete information symmetrically. In any interval representation only two of the three properties high, low, and width need to be stated and the third can be derived.

This is the high limit of the interval.

SHOULD contain zero or one [0..1] quantity (CONF:1098-8751).
