It should look something like this (you'll have to remove a bunch of other unnecessary settings from the file to make it look list this):

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
     <key>PayloadContent</key>
     <array>
      <dict>
       <key>PayloadDescription</key>
       <string>Configures restrictions</string>
       <key>PayloadDisplayName</key>
       <string>Restrictions</string>
       <key>PayloadIdentifier</key>
       <string>com.apple.applicationaccess.masked</string>
       <key>PayloadType</key>
       <string>com.apple.applicationaccess</string>
       <key>PayloadUUID</key>
       <string>masked</string>
       <key>PayloadVersion</key>
       <integer>1</integer>

     <string>Prevent Siri from Logging Me</string>

     <string>masked</string>

    </dict>
    </plist>
