  app.drey.Dialect.metainfo.xml:95 - A translation app for GNOME.
  The first `description/p` paragraph of this component might be too short (< 80 characters). Please consider starting with a longer paragraph to improve how the description looks like in software centers and to provide more detailed information on this component immediately in the first paragraph.
• asv-developer-name-tag-deprecated
  app.drey.Dialect.metainfo.xml:449 -
  The toplevel `developer_name` element is deprecated. Please use the `name` element in a `developer` block instead.

  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-developer-info-missing
  app.drey.Dialect.metainfo.xml -
  This component contains no `developer` element with information about its author.
