hi all, i have an astoundingly simple document format that i want to define via a DTD, and can't get the parsers to let me do it. so far i've looked in _the_XML_companion_, _the_XML_black_book_, and perused the spec. my ignorance still throbs mightily. in english: i want my documents to consist of a "model" element. a model can contain "topics" and "links", any number, in any order. in turn, topics can contain topics and links, in any number, in any order. i can tighten up the rules a little if need be -- for instance, requiring that models contain at least one topic. but because these represent mathematical operations, i can't just require that the topics come first and the links follow (e.g., <!ELEMENT model(topic*, link*)>. in (attempted) XML, with ATTLIST tags removed: <?XML version="1.0" encoding="UTF-8" standalone="no"?> <!ELEMENT model (topic* link*)> <!ELEMENT topic (topic* link*)> <!ELEMENT link> all non-profane feedback gratefully accepted. thanks for taking the time to have a look. if you wish to respond via private email instead of replicating to the list, that's dandy-fino with me. i doubt this problem is sufficiently generic to interest everyone. rw xml-dev: A list for W3C XML Developers.
