by Kurt Lownertz

Changes have been made to the following elements:

class-id: new element, to be used for coded classification
class-name: new element, content as previously class element

access-rights: element is now a sequence, referring to elements access-profile and access-right. The reason for the change is to harmonize with the final standard IEC 82045-2. Allows a detailed description of access rights for the document, for persons and/or groups of users.

access-group: new element, to contain the name of an access group for system defined by schema attribute

receipt: new element, referenced by distribution element, referring to date and person elements.

Element date has not been changed, but the use of attributes is redefined. Date formatting definitions shall use the schema attribute. The type attribute shall indicate the function of the date, using values such as submitted, performed, effective an expire. The reason for the change is to conform to the standard Iec 82045-2.
Element person-name has not been changed, but has a new reserved value user-id for the type attribute. This value can be used e.g. for description of access rights.
