When a document is constrained by a DTD, XXE is *not namespace aware*. In this mode, 'src:fragment' is a non-qualified XML 1.0 name (has no namespace at all) and 'xmlns:src' is an ordinary attribute with no special semantics.
In order to solve your problem: * Convert your DTD to a XML Schema using dtdtoxsd. * OR, more simply, do the following: [1] Always use the same prefixes (i.e. do not play with namespaces for example by adding xmlns:foo="http://nwalsh.com/xmlns/litprog/fragment"; in a nested element). [2] Remove: --- @namespace src url(http://nwalsh.com/xmlns/litprog/fragment); --- from the CSS. [3] Rewrite your CSS rules as if 'src:fragment' was a non-qualified name: --- src\:fragment { white-space: pre; font-family: monospace; background-color: #EEEEEE; border: thin solid gray; padding: 2px; margin: 1.33ex 0; } --- Note the '\' before the ':'.
