  NOTE             = "This file contains an incremental local Data Dictionary 
that was used to validate data labels for the New Horizons mission (NH).  It  
comprises locally-defined New Horizons data elements.  The NAMEs of these     
NH-specific elements begin with the NAMESPACE_ID string, 'NEWHORIZONS:'.  This
incremental dictionary contains text that is human-readable and should be     
inserted into, or replace equivalent text in, a PDSDD.FULL file, which can in 
turn be used as an input to PDS label validation software.  This is intended  
as a long-term (years) but temporary file that will eventually become obsolete
once it is stable and its PDSDD-relevant contents have been added to the      
standard PDS Data Dictionary, PDSDD.FULL.
