User who last modified the value. This read-only String property is set by the server on successful edits of the object.
The object placeholder is an object expression that evaluates to a IPIVersion object.
The User ID is actually stored rather than text name. On retrieval the ID is translated to text. Thus user re-names on the server will be reflected in this property. This is a read only property.
The IPIVersion interface may be supported by any PI-SDK object. Currently, only PIModule supports this interface.
