Okay, this may be blatant self-publication, but I was wondering if W3Schools would like another example of a DTD to show on the DTD Examples page.If so, have a gander at http://www.nickmoore.org.uk/dnd/I've created two separate, but very similar, DTDs, which W3Schools would be welcome to display as examples. I should think you'd be most interested in this example - 3ed-party.txt (saved as .txt so you can read it more easily, there is a 3ed-party.dtd in the same folder).
