I'm still envisaging a single YANG instance data file containing 
multiple instances of YANG data.  In this scenario some of the meta data 
may be at the file level, and some of the meta-data may be at the per 
instance level.  I was suggesting that a time/date stamp of when the 
data was generated would be at the file level rather than at the 
instance level.

Thanks,
Rob
