Bob is correct. I haven't found a way to get XSD to do the validation as you want. It's unfortunate because it'd be nice for intelli-sense but in the end you want to have the check in your extension anyway because you can provide a much better error message than what XSD would give by default.

In general, WiX does explicit authoring checks because it can do so more flexibly than schema validation allows -- certainly it gives better errors then 'invalid content.'<g> -- sig://boB http://joyofsetup.com/ ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
