uslm:IdentificationGroup

 
            The identification group of attributes is used to add an identity to
            an element. All elements use the identification group, and all 
            attributes are optional. In general:
            
            - An @id is an immutable GUID assigned to an item at its birth.
            - An @temporalId is a time variant name, scoped to the document.
            - An @identifier is an item variant URL, scoped globally.
            - As @scope is a URL of the scope in which the @identifier is valid.

Attributes

NameOccTypeDescriptionNotes
id [0..1]xsd:ID The @id attribute should always be assigned an immutable (non-changing) value. If the item is subject to renaming or renumbering, then the @id attribute should not reflect any part of the changeable part. This is to allow the @id to be long lasting without causing confusion should the item be renamed or renumbered. The @id should be prefixed with "id" and followed by a GUID that is guaranteed to be globally unique across both time and space. As an "xsd:ID", the identity must be ensured to be unique in the document - and it is a good idea that it be guaranteed globally unique. As the @id is immutable, it is a good identity with which to associate external information to the item. If an item is deleted and later a similarly named item is created, then the new item should be assigned a newly generated identity as it is not the same item as the earlier item. The @id attribute is optional, but recommended for all elements which will contain any other identity attributes.
temporalId [0..1]uslm:MediumStringSimpleType The @temporalId attribute is a name, scoped to the document, that is intended to reflect the current identify of the element in a human-readable way. This means that the @temporalId may need to be recomputed based on the temporal state of a document or according to the temporal specification in a requesting URL. A @temporalId is intended to be scoped to the document as a whole while the @name is scoped to its immediate parent. The @temporalId is built as an "_" separated hierarchy of @name or, in the absence of an @name, element names. However, in a couple cases, the levels of the hierarchy are suppressed. First of all, the <main> level is suppressed when calculating any @temporalId contained within. Secondly, when dealing with sections which are numbered as a sequence without regard to the upper levels, then the upper levels are suppressed from the computation of the @temporalId. Some examples: * "s2" - section 2 in the main part of the document * "schedule_s2" - section 2 in the schedule * "pt2_d1" - division 1 of part 2 in the main part of the document The @temporalId attribute is optional.
identifier [0..1]uslm:LongStringSimpleType Use the @identifier attribute to specify the URL context of the element. Typically, the @identifier will be established on the root element or on any element, such as a <quotedContent> element, that changes the context. The @identifier attribute is optional.
scope [0..1]uslm:LongStringSimpleType Use the @scope attribute to specify the scope within which the @identifier attribute is valid. Typically, @scope is formatted as a URL, referring to a specific context. @scope is used for terms within in definitions to specify the scope of the definition. The @scope attribute is optional.
