Dear all,
   MPEG-21 DIA Usage Environment Description defines Mobility  
Characteristics for a User. The excerpt from the schema you can find  
below and the full schema is available at [1]. As this is somewhat  
related it might be helpful for (some of) you. If you need information  
on the semantics, please let me know.

Thank you.
Best regards,
  -Christian
