Hi,

the first entry is all valid content types that the plugin supports, the
second entry is the fallback for the storage configuration, i.e. if the
storage configuration for a specific storage does not explicitly specify
a 'content' option, those will be used/allowed. See the parse_config()
method in Plugin.pm.

Best Regards,
Fiona
