+	<!-- 
+    Version 1.8		2015-03-05 tmee@loc.gov
+    				Typo mods:provence changed to mods:province
+    
+	Version 1.7 	2015-01-30 ws
+					Changed dc:creator to dc:contributor if mods:name/mods:roleTerm != creator
+					Fixed xpath bug in dc:subject output for mods:subject/mods:titleInfo/mods:title
+					Fixed xpath bug in dc:format when mods:extent | mods:form | mods:internetMediaType [@unit]
+					Fixedbug in xpath for @type
+					
+	Version 1.6		2015-01-30 schema location change: 
+    				http://www.loc.gov/standards/sru/recordSchemas/dc-schema.xsd
+        
+	Version 1.5		2014-07-23 tmee@loc.gov
+					Fixed subject transformation to eliminate empty element output
+		
+	Version 1.4		2013-12-13 tmee@loc.gov
+					Upgraded to MODS 3.5
+		
+	Version 1.3		2013-12-09 tmee@loc.gov
+					Fixed date transformation for dates without start/end points
+	
+	Version 1.2		2012-08-12 WS 
+					Upgraded to MODS 3.4
+	
+	Version 1.1	2007-05-18 tmee@loc.gov
+					Added modsCollection conversion to DC SRU
+					Updated introductory documentation
+	
+	Version 1.0		2007-05-04 tmee@loc.gov
+	
+	This stylesheet transforms MODS version 3.4 records and collections of records to simple Dublin Core (DC) records, 
+	based on the Library of Congress' MODS to simple DC mapping <http://www.loc.gov/standards/mods/mods-dcsimple.html> 
+			
+	The stylesheet will transform a collection of MODS 3.4 records into simple Dublin Core (DC)
+	as expressed by the SRU DC schema <http://www.loc.gov/standards/sru/dc-schema.xsd>
+	
+	The stylesheet will transform a single MODS 3.4 record into simple Dublin Core (DC)
+	as expressed by the OAI DC schema <http://www.openarchives.org/OAI/2.0/oai_dc.xsd>
+			
+	Because MODS is more granular than DC, transforming a given MODS element or subelement to a DC element frequently results in less precise tagging, 
+	and local customizations of the stylesheet may be necessary to achieve desired results. 
+	
+	This stylesheet makes the following decisions in its interpretation of the MODS to simple DC mapping: 
+		
+	When the roleTerm value associated with a name is creator, then name maps to dc:creator
+	When there is no roleTerm value associated with name, or the roleTerm value associated with name is a value other than creator, then name maps to dc:contributor
+	Start and end dates are presented as span dates in dc:date and in dc:coverage
+	When the first subelement in a subject wrapper is topic, subject subelements are strung together in dc:subject with hyphens separating them
+	Some subject subelements, i.e., geographic, temporal, hierarchicalGeographic, and cartographics, are also parsed into dc:coverage
+	The subject subelement geographicCode is dropped in the transform
