Complex Type ReferenceValueType

Namespace | urn:us:gov:ic:tdf
Annotations | Incorporates a value by reference to a URI where it can be found. To support division of a value into smaller pieces for transport (AKA "chunking"), such as across a CDS, the body of the element may contain a list of ReferenceValueBlock elements. If so, each must have a URI to the block and an integer block number indicating the order in which the blocks can be re-assembled into the original payload. Block numbers must start at 1 and be sequential. When a list of ReferenceValueBlocks is used, a TotalHash element must be present and must have a totalBlocks attribute set to an integer indicating the number of such elements. Tailoring: Not all systems will be willing or able to support unbounded lists of blocks. When tailoring maxOccurs here to reflect limitations imposed by a CDS or other implementation, that change should also be reflected in the definition of a BlockedHashGroup.

Attributes |
QName | Type | Use | Annotation
--- | --- | --- | ---
id | xs:ID | optional | A unique local identifier used for binding and signing purposes. Not guaranteed to be unique across multiple TDC/TDOs but must be unique within a single instance of either.
isEncrypted | xs:boolean | optional | Used to denote if contents are encrypted. When this optional attribute is absent, it is assumed to be false.
mediaType | MediaTypeType | optional | An attribute for expressing the mediaType of an object as defined in RFC 4288.
totalBlocks | TotalBlocksType | optional | The total blocks of a hash.
uri | xs:anyURI | required | A uri expressing the location of the referenced material.
