+= How-to update schematron rules to ISO 19757-3 ? =
+GeoNetwork (before 2.5.0) was using Schematron 1.x series which has been taken over by ISO Schematron implementation.
+This how-to describes the way to update rules define in 1.x to be used in ISO Schematron.
+
+More information:
+ * http://www.schematron.com/
+
+== Update namespace ==
+Namespace in ISO Schematron is: http://purl.oclc.org/dsdl/schematron
+
+{{{
+-<sch:schema xmlns:sch="http://www.ascc.net/xml/schematron">
++<sch:schema xmlns:sch="http://purl.oclc.org/dsdl/schematron">
+}}}
+
+== Use sch:title instead of sch:pattern/@name ==
+sch:title is now used to store the title of the rule.
+
+Example:
+{{{
+-       <sch:pattern name="$loc/strings/M6">
++       <sch:pattern>
++               <sch:title>$loc/strings/M6</sch:title>
+}}}
+
+== (optional) Improve report ==
+In order to improve report information, the use of sch:let to test the existence of an element in combinaison with sch:assert in case of error and sch:report in case of success improve report readability.
+
+sch:value-of could be use to report variable information in report.
+{{{
+    <sch:pattern>
+        <sch:title>$loc/strings/M500</sch:title>
+        <sch:rule
+            context="//gmd:MD_Metadata|//*[@gco:isoType='gmd:MD_Metadata']">
+            <sch:let name="language" value="gmd:language/gco:CharacterString"/>
+            <sch:let name="localeAndNoLanguage" value="not(gmd:locale and gmd:language/@gco:nilReason='missing')
+                and not(gmd:locale and not(gmd:language))"/>
+      
+            <!--  Check that main language is not defined and gmd:locale element exist. -->
+            <sch:assert test="$localeAndNoLanguage"
+                >$loc/strings/alert.M500</sch:assert>
+            <sch:report test="$localeAndNoLanguage"
+                ><sch:value-of select="$loc/strings/report.M500"/> "<sch:value-of select="$language"/>"</sch:report>
+}}}
+
+== Compile ==
+Then use the "ant schematron" in schematron directory to publish your rules to schema folders.
