It would make sense to use XML Schema files instead of DTDs. http://jira.openlaszlo.org/jira/browse/LPP-7502
Not sure anyone would have time to work on the compiler/build process to support XML Schema generation. How did the unreleased IDE deal with that problem? Could that approach be re-used here?
