To allow a collection of registry objects to be grouped together and be identified as versions of the same object, two new attributes are introduced: the Logical ID and the VersionInfo element. While all objects must have unique value for their id attribute to maintain their identity, all objects that are versions of the same logical object have the same logical id or lid attribute

Public Property VersionInfo As String

Dim instance As XdsDocument
Dim value As String
 
instance.VersionInfo = value
 
value = instance.VersionInfo

public string VersionInfo {get; set;}

public:
property String^ VersionInfo {
   String^ get();
   void set (    String^ value);
}
