XMI26 — 9.4.1 serialization of a null-valued property typed by an enumeration or primitive type

Open Closed All
  • Key: XMI26-1
  • Status: open  
  • Source: NASA ( Dr. Nicolas F. Rouquette)
  • Summary:

    Table 9.4.1 states:

    When the value of a Property is null, it is serialized as XMIValueElement with attribute nil=’true’.

    In UML, null means "lack of a value".
    MOF (which is based on a subset of UML) inherits this – that is, for MOF, null also means "lack of a value".

    Currently, many UML tools do not serialize null-valued properties according to the rule above, instead, the property is not serialized at all.
