<!-- 
     OVERVIEW - iso_abstract_expand.xsl
     
	    This is a preprocessor for ISO Schematron, which implements abstract patterns. 
	    It also 
	       	* extracts a particular schema using an ID, where there are multiple 
             schemas, such as when they are embedded in the same NVDL script 
           * allows parameter substitution inside @context, @test, @select, @path
	    	   * experimentally, allows parameter recognition and substitution inside
             text (NOTE: to be removed, for compataibility with other implementations,   
             please do not use this) 
		
		This should be used after iso-dsdl-include.xsl and before the skeleton or
		meta-stylesheet (e.g. iso-svrl.xsl) . It only requires XSLT 1.
		 
		Each kind of inclusion can be turned off (or on) on the command line.

VERSION INFORMATION
  2013-09-19 RJ
     * Allow macro expansion in  @path attributes, eg. for   sch:name/@path

  2010-07-10 RJ
  		* Move to MIT license
  		
  2008-09-18 RJ
  		* move out param test from iso:schema template  to work with XSLT 1. (Noah Fontes)
  		
  2008-07-29 RJ 
  		* Create.  Pull out as distinct XSL in its own namespace from old iso_pre_pro.xsl
  		* Put everything in private namespace
  		* Rewrite replace_substring named template so that copyright is clear
  	
  2008-07-24 RJ
       * correct abstract patterns so for correct names: param/@name and
     param/@value
    
  2007-01-12  RJ 
     * Use ISO namespace
     * Use pattern/@id not  pattern/@name 
     * Add Oliver Becker's suggests from old Schematron-love-in list for <copy> 
     * Add XT -ism?
  2003 RJ
     * Original written for old namespace

		Abstract patterns allow you to say, for example
		
		<pattern name="htmlTable" is-a="table">
			<param name="row" value="html:tr"/>
			<param name="cell" value="html:td" />
			<param name="table" value="html:table" />
		</pattern>
		
		For a good introduction, see Uche Ogbujii's article for IBM DeveloperWorks
		"Discover the flexibility of Schematron abstract patterns"
		  http://www-128.ibm.com/developerworks/xml/library/x-stron.html
		However, note that ISO Schematron uses @name and @value attributes on
		the iso:param element, and @id not @name on the pattern element.
