                <description>Version 1.1.0.0 of the Spectra dictionary is
                    the first publicly released version of the dictionary. 
                    It corresponds to version 1.1.0.0 of the PDS common
                    dictionary.
                    
                    1) Changed the minOccurs and maxOccurs of the xs:choice
                       element in the Spectral_Lookup class from 1 to 2.
                    
                    2) Fixed the definition of the Axis_Bin_Set class to
                       correct the name of the class.
                    
                    3) Changed the order of the complexType definitions in
                       the schema file; they are now alphabetized.
                    
                    4) Removed minOccurs and maxOccurs from elements within
                       xs:choice tags.

                <description>Version 1.0.0.1 of the Spectra dictionary is a
                    draft version of the dictionary intended for
                    distribution to the DDWG.
                    
                    1) All dependencies on the Imaging Node dictionary
                       (primarily filter-related items) have been removed,
                       as that dictionary has not yet been formally
                       released.  These dependencies may be re-introduced
                       in a future version of this dictionary.
                    
                    2) The Filter_Attributes class has been renamed to
                       "Filter".
                    
                    3) Renamed "reference_type" in the
                       Local_Internal_Reference class to
                       "local_reference_type", to be consistent with
                       proposed common class in CCB-30.
                    
                    4) Made "Bin" class extensible by adding the "xs:any"
                       attribute.
                    
                    5) Removed the extraneous element definitions for
                       "lid_reference" and "lidvid_reference" (since these
                       are in the "pds" namespace).
                    
                    6) Change "teh" to "the" in the definition of the
                       filter_name attribute.
                    
                    7) Integrated the "xs:choice" functionality directly
                       into the Ingest_LDD, rather than hand-editing it
                       into the schema after the fact.
                    
                    8) Simplified all class and attribute local_identifiers
                       (should be invisible to dictionary users).
                    
                    9) Added the sp.Units_of_Wavelength to the Imaging Node
                       dictionary database as an attribute, rather than
                       hand-editing it into the schema manually.  This
                       should be replaced with the "pds" version of the
                       units when version 1.1.0.0 of the common model is
                       released.
