   <?xml version="1.0"?>
   <sdf version="1.5">
   <model name="a_simple_box">
   <static>false</static>
   <link name="link">
     <pose>0 0 1 0 0 0</pose>
     <collision name="collision">
       <geometry>
         <box>
           <size>.3 .2 .5</size>
         </box>
       </geometry>
     </collision>
     <visual name="visual">
       <geometry>

         </box>
       </geometry>
     </visual>
   </link>

   to get mentioned error message.

2. Run gz sdf --verbose -k model.sdf
3. Run cp model.sdf modelv.sdf &&gz sdf --verbose -k modelv.sdf` to get "Check complete".
