<?xml version="1.0" encoding="UTF-8"?><?xar XSLT?> <!-- 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. --> <!-- Open Source Initiative OSI - The MIT License:Licensing [OSI Approved License] This source code was previously available under the zlib/libpng license.

(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 * http://www.topologi.com/resources/iso-pre-pro.xsl --> <xslt:stylesheet version="1.0"
