+     OVERVIEW : iso_dsdl_include.xsl
+     
+	    This is an inclusion preprocessor for the non-smart text inclusions
+	    of ISO DSDL. It handles 
+	    	<relax:extRef> for ISO RELAX NG
+	    	<sch:include>  for ISO Schematron and Schematron 1.n
+	    	<sch:extends>  for 2009 draft ISO Schematron
+	    	<xi:xinclude>  simple W3C XIncludes for ISO NVRL and DSRL 
+	    	<crdl:ref>     for draft ISO CRDL
+	    	<dtll:include> for draft ISO DTLL
+	    	<* @xlink:href> for simple W3C XLink 1.1 embedded links
+	    	
+		 
+		This should be the first in any chain of processing. It only requires
+		XSLT 1. Each kind of inclusion can be turned off (or on) on the command line.
+		
+		Ids in fragment identifiers or xpointers will be sought in the following
+		order:
+		    * @xml:id
+		    * id() for typed schemas (e.g. from DTD) [NOTE: XInclude does not support this]
+		    * untyped @id 
+		    
+	The proposed behaviour for the update to ISO Schematron has been implemented. If an
+	include points to an element with the same name as the parent, then that element's
+	contents will be included. This supports the merge style of inclusion.    
+	
+	When an inclusion is made, it is preceded by a PI with target DSDL_INCLUDE_START
+	and the href and closed by a PI with target DSDL_INCLUDE_START and the href. This is
+	to allow better location of problems, though only to the file level. 
+	
+	Limitations:
+	* No rebasing: relative paths will be interpreted based on the initial document's
+	path, not the including document. (Severe limitation!)
+	* No checking for circular references
+	* Not full xpointers: only ID matching
+	* <relax:include> not implemented 
+	* XInclude handling of xml:base and xml:lang not implemented   
+-->
+<!-- 
+  VERSION INFORMATION
+	2009-02-25 
+	* Update DSDL namespace to use schematron.com
+	* Tested with SAXON9, Xalan 2.7.1, IE7, 
+	* IE does not like multiple variables in same template with same name: rename.   
+	2008-09-18
+	* Remove new behaviour for include, because it conflicts with existing usage [KH]
+	* Add extends[@href] element with that merge functionality
+	* Generate PIs to notate source of inclusions for potential better diagnostics
+	
+	2008-09-16
+	* Fix for XSLT1
+	
+	2008-08-28
+	* New behaviour for schematron includes: if the pointed to element is the same as the current,
+	include the children.
+	
+	2008-08-20
+	* Fix bug: in XSLT1 cannot do $document/id('x') but need to use for-each
+	
+	2008-08-04
+	* Add support for inclusions in old namespace  
+	
+	2008-08-03
+	* Fix wrong param name include-relaxng & include-crdl (KH, PH)
+	* Allow inclusion of XSLT and XHTML (KH)
+	* Fix inclusion of fragments (KH)
+	
+	2008-07-25
+	* Add selectable input parameter
+	
+	2008-07-24  
+	* RJ New
