      Description:  Validating XML Schema for the Identification 
                    Information section. Please reference the Census 
                    Bureau Geospatial Product Metadata Standard (GPMS),
                    Table 1.
      Modification History:
          Initial   Date      Change Request ID  Description
          JWA      20050314    N/A                Initial version
          JWA      20051109    N/A                Updated to reflect current GPMS Table 1.
          JWA      20051201    N/A                 Added types and attributes for Oracle XML DB.
          JWA      20051215    N/A                 Changed xsd:string to mtag:vstring
                                                   to validate elements have a value.
          MMC      20071204    N/A                Modified so that all the Keywords have to have
                                                   a minimium string length of 1
          MMC      20071204    N/A                Modified so that the Abstract and Purpose have to have
                                                   a minimium string length of 1
          MMC      20071205    N/A                Modified West_Bounding_Coordinate so that the minimum 
                                                   value is -180
          MMC      20071206    N/A                Modified Title_13_Type to accept "Yes" and "No"
          MMC      20071210    N/A                Modified Title_13_Type to have a minimum string
                                                   length of 2 and a maximum string length of 3
          MMC      20071211    N/A                Modified so that Edition, Geospatial_Data_Presnetation_Form
                                                   Online_Linkage, Currentness_Reference and Progress all
                                                   have to have a minimum tring length of 1 character.
          MMC      20080208    N/A                Modified to accept variable length Title_13 elements. 
          MMC      20080528    N/A                Eliminated the West_Bounding_Coordinate_Type because it
                                                   was causing an error; 2 Min+max Exclusives: 1 in the 
                                                   West_Bounding_Coordinate_Type and 1 in the 
                                                   mtag:Longitude_Type.Also changed the type in the 
                                                   West_Bounding_Coordinate element from 
                                                   West_Bounding_Coordinate_Type to the mtag:Longitude_Type.   
          MMC      20080616    N/A                Xpaths modified to mirror the directory structure on node104.
          MMC      20101221    N/A                Modified to verify the ISO Keywords. This was done by creating
                                                   a new complexType called Theme_Keywords_Type and deleting "Keywords_Type" 
                                                   complex, which included the Theme and Place keywords. The "Theme_Keywords_Type" complex ensures
                                                   that all the keyword types(ISO, regular and place) exist in any order.
                                                   This is achieved through calling three other complex types: ISO_Theme_Keyword_Type,
                                                   which ensures that there are the correct ISO keywords, Regular_Theme_Keyword_Type
                                                   , which ensures that there are Theme keywordsand Place_Theme_Keyword_Type, which ensures
                                                   that there are Place keywords. Finally, the complexTypes representing each profile were changed.        
         MMC       20101221    N/A               Changed the maxOccurs attribute on the "Theme_Keyword" to 19. This was done to represent the 
                                                  number of ISO 19115 keywords.  
         MMC       20110302    N/A               Modifed to verify more than 1 set of Place Keywords can exist. Now, 3 different sets Place_Keywords are
                                                  checked for:Place, Place_INCITS and Place_INCITSB.
         MMC       20170217    N/A               Modified so that the Curentness Reference and the Progress elements only accept the Standard values
