See http://hsivonen.iki.fi/no-dtd/ explains why DTDs don't work for the Web in the general case. Loading same-origin DTDs for the purpose of localization is a semi- defensible case, but it's a lot of complexity for a use case that is way on the wrong side of 80/20 on the Web scale. Besides, if the use case for DTDs is localization within an origin, the server can perform the XML parse and reserialize into DTDless XML. (That's how I've implemented this pattern in the past without client-side support.) -- Henri Sivonen hsivonen at iki.fi http://hsivonen.iki.fi/
