Imprimatur: application/xml-dtd
Thanks to Patrice for pointing out that the URL of the Imprimatur DTD http://imprimatur.sourceforge.net/imprimatur-008.dtd
is returning the wrong content type. IIRC it used to be text/plain
, but then it must have somehow changed to text/html
, I've now changed it to application/xml-dtd
which I believe is correct.
