Hi all, Thanks for the updated XSDs Tom. It works a lot better now. I've added an option in Lynx to do schema validation (using a copy of the official XSDs) followed by processing the input file and checking for various issues. I wouldn't say it's going to catch everything. But when it's done it should catch any error against the schemas, as well as most PR issues for the Core (and only for the Core). The command-line looks like this: lynx -v firsDoc.xlf secondDoc.xlf ectDoc.xlf One problem I'm running into is the slowness of the validation: both loading the schema and performing the validation seem to take a lot more time than expected. Maybe this is related to fetching some default schema for the XML namespace? Or to the processing of the includes? If anyone has some tips about XSD validation with Java, I'm listing. cheers, -ys
