Joe English said pretty much everything I wanted to say. Just one additional comment. Rick Jelliffe wrote: > doesn't the presence of these tricky ambiguity issues > mean that to actually understand RELAX (and presumably certain other schema > languages) requires a computer scientist not a data modeler? If you're using RELAX for validation, it doesn't have any ambiguity issues. In this regard it is the same as TREX. The ambiguity issues only arise if you try to use it to "interpret" the document (that is augment the information in the document by assigning each element or attribute a label corresponding to some rule in the schema). If you just stick to validation, there's no issue. I would agree with the sentiment that it's bad to inflict tricky ambiguity issues on data modelers. Fortunately this is not inherent in using grammars for validation. James
