	 FGDC Metadata XML Schema 1.0.0 20030801

	 This is the XML Schema for formal metadata, metadata conforming to

	 the Content Standards for Digital Geospatial Metadata of the Federal

	 Geographic Data Committee.  This schema corresponds to the June,

	 1998 version of the standard, FGDC-STD-001-1998.

	 This file is the primary XML Schema and loads the definitions for

	 sections 1-10 of the standard from separate schema modules.

	 Element names:

	     Element names are a maximum of 8-characters long, to coincide

	     with the Reference Concrete Syntax.

	 Element ordering:

	     Generally the order of elements is now significant.  XML makes

	     it difficult to write a DTD that allows elements to be in any

	     order.  Although XML Schemas do not have this restriction, it

	     was decided to keep the significance of element order in order

	     not to break the DTD validity of XML-encoded metadata files.

	 Authors:

	     Richard E. Rathmann (PSGS/NOAA Coastal Services Center,

	     Charleston, SC) with assistance from Mike Moeller (PSGS/NOAA

	     CSC) and Doug Nebert (Federal Geographic Data Committee).

	 Revisions:

	     20020826 (RER) Locally scoped the definition of "onlink" in

	                      Section 7 (7.11.1) within "metextns" (7.11)

	                      rather than referencing "onlink" definition in

	                      Section 8 (8.10).

	     20030801 (RER) Removed 'xml:space="preserve"' from all

	                      'xsd:documentation' elements.  I originally put

	                      this in to say "whitespace is significant", but

	                      both XML Spy and IBM's  Schema Quality Checker

	                      complain about them.

	     20030801 (RER) Corrected the second regular expression pattern

	                      for the "FGDCtime" simple type in this schema

	                      module.  The "-" in the "[+-]" character class

	                      for the sign character needed to be escaped, as

	                      in "[+\-]".

	     20030801 (RER) Changed types of "srcused" (2.5.2.2) and "srcprod"

	                      (2.5.2.5) in Section 2 to reference the type

	                      defined for "srccitea" (2.5.1.5) to comply with

	                      XML Schema constraint that key/keyref field

	                      value pairs be of the same type.
