When creating a new Ext plugin project in IDE, there is a validation error on one of the XML files that are a part of the default ext-plugin template. Specifically the file:
docroot/WEB-INF/ext-web/docroot/WEB-INF/tiles-defs-ext.xml

is invalid and is marked with an error by the eclipse XML validator. According to the DTD, it should have at least one <definition/> element.
