OpenLaszlo Schema Generator provides methods to enhance LZX-Markup from the OpenLaszlo RIA with full schema/namespace support and validation. You can run it from the command line or from inside your project using ANT. The JAR contains tasks to generate an XSD from your project LZX files; by doing that, you have full Schema Validation in Eclipse, and it will show you all your XML schema errors. The validation is aware of ALL tags and attributes: the LZX base components (+incubator) and your project specific code. Further, you get content-sensitive drop down menus for Tags and Attributes.
