Implements
IVsUserDataEvents.OnUserDataChange(Guid%, Object)
Remarks
A text buffer can have a number of user-settable values associated with it. Each value is identified by a unique GUID. Whenever one of these values is changed with a call to the SetData method in the IVsUserData interface, the OnUserDataChange method is called.
The base method does nothing.
