Reply to: Trouble understanding error message.December 14, 2009 at 8:33 pm
This warning might mean your DTD is trying to redefine an entity that has been previously defined, though it could also be something else. I believe this is a warning not an error (correct?) If so, this is not new behavior, so I'm surprised it would suddenly appear without any changes to the DTD.
However, in order to give you a really good answer XMetaL Support will need to see your DTD. Can you please submit a support case to XMetaL Support?
