Bug report #4408
Validating *.qgs or *.qml against *.dtd

It's not possible to validate a QGIS project or style file against the called *.dtd (http://mrcc.com/qgis.dtd). Two reasons: the URL doesn't exist and using a *.dtd from SVN always returns a "non valid". Having the possibility to validate could decrease erroneous project files. As such it's a feature wish, but as long as QGIS mentions a *.dtd not working, it's a bug.

According to this text:
this dtd declaration with an url is actually optional, so another option would be to remove it from the xml?
