Hi I have developed some schematron rules to apply to DITA content for our staff. We use the IXIASOFT CMS Client, which means that we are using oXygen inside of Eclipse. When I open a file in Author Mode, the schematron rules are applied automatically. Red and yellow underlines flag the items considered invalid by the Schematron rules. When I switch to editing the file in Text mode, the Schematron rules are not applied automatically. I have to manually run validation. We are behind in the IXIASOFT releases, so we are using Eclipse 3.5.2 and oXygen 16.1. Is there a setting I can change to fix this? Is this fixed in oXygen 17.1? Is it fixed in newer versions of Eclipse? All my very best, Rob -- Rob Echlin, Documentation Systems Architect, Wind River Office: 613-270-5796, Cell: 613-266-8311, Skype: rob.echlin.wr
