xaml: Resource is never used

Hello,

is there a declarative way to instruct ReSharper that TargetType="TreeViewItem"> is not "never used" because there is a TreeView
present?

Same thing goes for many 3rd party components: If there is a xcdg:DataGrid
then xcdg:DataRow and xcdg:DataCell (and many more) are not "never used".
