<style.resources>                 <style targettype="label">                     <setter property="padding" value="15,15,5,15" />                     <style.triggers>                         <datatrigger binding="{binding relativesource={relativesource mode=self}, path=tag}" value="true">                             <setter property="foreground" value="white" />                             <setter property="fontsize" value="20" />                         </datatrigger>                     </style.triggers>                 </style>             </style.resources>
