A number that indicates element content changes in a specific issue of an information module or IPM
Used when this element and/or its contained elements have been changed in a revision or update and it is required that the change shall be visible to the end user, e.g. through change bars. The number shall correspond to the change issue number ( attribute andr.nr on element andring) in the Administrative data module where the change description is.
Example: If andr.utg has a value of "3", it means that changes has been made since issue number "2"
This attribute is used in order to enable the generation of change bars on paper. If no change bars are requried, it is enough to document the change in the admindata module, possibly with references (hanvisning) to changed elements.
Note: Deletion of an element is never directly indicated. Instead, the change attribute on a parent element is filled in.
NUMBER
HyTime attribute: Identifies the element or it's content as being significant to HyTime processing, and defines the corresponding HyTime architectural form
The HyTime values differs between elements, but it is always a fixed value that must not be changed.
For further explanations, see the HyTime standard (ISO 10744), clause 6.4.
