• asv-nonstandard-gnome-extension
  org.mate-desktop.mate-eiciel.appdata.xml:35 - kudos
  This tag is a GNOME-specific extension to AppStream and not part of the official specification. Do not expect it to work in all implementations and in all software centers.
• asv-cid-contains-hyphen
  org.mate-desktop.mate-eiciel.appdata.xml:5 - org.mate-desktop.mate-eiciel.desktop
  The component ID contains a hyphen/minus. Using a hyphen is strongly discouraged, to improve interoperability with other tools such as D-Bus. A good option is to replace any hyphens with underscores (`_`).
