Indeed, W3C now imposes a limit on the number of requests that can be made on a DTD in a given time range. http://www.w3.org/Help/Webmaster.html#block Note that there are plenty of options to avoid hitting the W3C servers with DTD requests over and over: * disabling DTD validation in your project * using an XML Catalog * using a proxy between your application and the Web Hope this helps, Dom
