TIL: That Edit as XML has Intellisense. I've always thought of it as just a Notepad type editor.
One more question while I'm here. Some of the existing taskPresets have a performRule element but I don't see any documentation on it. What does that do?
<performRule isEnabled="false" settingName="" operator="0" operand="" />
