I actually had already started down the path of option number two that you suggested, i.e. using "wrapper" documents, with DTDs, to refer to external entities, w/o DTDs, that contain the actual document. I need a DTD on these documents because I need to constrain their structure. I was hoping there was a better way, since this doubles the number of documents I have to manage, but it appears there isn't. I consider this to be a shortcoming of XML, in that it is not "orthogonal", i.e. I have to write my documents in one of two different ways, depending on how they're going to be used. A better solution, I believe, would be to take a more "object-oriented" approach, i.e. that each document is responsible for it's own validity, through the use of its own DTD. This would require a parser that could handle recursively nested documents, each with their own DTD. Although I could adopt such a non-standard solution here in my own environment, and produce HTML for publication, I couldn't publish the XML/XSL, since the documents would be non-standard and unreadable by anyone else. I keep hearing that XML is a "data" language, as opposed to a "document" language, but I think that this is one case where XML breaks widely accepted data modelling norms, i.e. type encapsulation. Thanks all, Alan. P.S. James, after I sent that mail, I realised that my documents are not actually standalone (in XML terms), since they refer to an external DTD, so I used the term incorrectly. But, then I realised they could actually be standalone, by making all of the necessary declarations in the internal subset, and the problem would still be the same. xml-dev: A list for W3C XML Developers.
