will appear at the bottom of Kate's main window. You can click on an error message
to jump to the corresponding place in the file. If the file has a “DOCTYPE”
the DTD given with this doctype will be used to check the file for validity. The
DTD is expected at a position relative to the current file, e.g. if the doctype
refers to “DTD/xhtml1-transitional.dtd” and the file is

However, remote DTDs specified via http are supported.
If the file has no doctype it will be checked for being well-formed.
