<p>As andrew said might want to file a bug report with them. Do not map for presentation/an application. The application needs to conform to the data<o:p></o:p></p>

to tag these, instead of tagging them as a restriction? Perhaps something like "restriction:signal"="no_turn_on_red", so that it doesn't get picked up on a search for the 'restriction' key? I don't think the developers are likely to bother checking for such
an uncommon tag at this point. <o:p></o:p></span></p>
