This raises its head in many situations, including storage (particularly in relation to objects). I think the answer is in the realm of validation. Define a 'domain' language and you can validate the contents; use a 'metadata' language and you can only validate the structure of that language. The contents could be a right mess and still get through. Of course you could then build a validating layer on top of the 'metadata' language, which is what RDF tends to do. If the validating you need to do is far more elaborate than can be provided by a DOM then you lose nothing by using a 'metadata' language, since you are going to have to do a lot of post-parser processing anyway. Otherwise, I'd go with a 'domain' language. Mark xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
