Hi, Does anybody know why we have two schema? - knowledge-api\src\main\resources\change-set-1.0.0.xsd - knowledge-api\src\main\resources\change-set.xsd They only differ by this (the bold text being in change-set-1.0.0.xsd):- ... <xsd:element name="resource"> <xsd:complexType> <xsd:sequence> <xsd:any *minOccurs="0"* /> <xsd:element minOccurs="0" ref="change-set:decisiontable-conf"/> </xsd:sequence> ... We also (historically) quote the schema location as http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/... . Does anybody object if I remove change-set.xsd and update schemaLocation references to our github equivalent? Cheers, Mike
