With this simplified .tmLanguage file, the whole document should be formatted a comment (because I use a begin without and end).

</plist>This works fine unless the document contains the word undefined.
I guess this is a "end is undefined" issue where undefined is taken literally.
The issue can be avoided by setting end to a never-matching regexp (like <key>end</key><string>^\b$</string>). And maybe that could be put into the highlighting code: if undefined, use ^\b$ instead of the string undefined.
