asv-tag-duplicated
:46 - supports
This tag must only appear once in this context. Having multiple tags of this kind is not valid.

asv-cid-contains-hyphen
:3 - org.solarus-games.solarus-launcher
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 (`_`).
asv-unknown-tag
:35 - developer
Found invalid tag. Non-standard tags should be prefixed with `x-`. AppStream also provides the <custom/> tag to add arbitrary custom data to metainfo files. This tag is read by AppStream libraries and may be useful instead of defining new custom toplevel or `x-`-prefixed tags if you just want to add custom data to a metainfo file.
asv-content-rating-missing
-
This component has no `content_rating` tag to provide age rating information. You can generate the tag data online by answering a few questions at https://hughsie.github.io/oars/
