Suppress XML DTD error in Eclipse

Question

The XML DTD for a Joomla component is not correct, it does not contain the method="install/upgrade" attribute. In eclipse it is annoying me because there is a permanent error showing for my project.

Is there a way to suppress this particular XML DTD error, while allowing other xml error checking to take place in the file?

Answer 1

Preferences -> XML -> XML Files -> Validation -> "Indicate when no grammar is specified" = "Ignore"
