-to augment the mediatype definition (what you see after the "+", e.g. "image/svg+xml").
-
-This had its limitations. For one, it was only possible with one file extension per MIME type.
-
-Now you can specify multiple file suffixes using "suffixes", but you need to specify the full MIME type

-
-[mediaTypes]
-[mediaTypes."image/svg+xml"]
-suffixes = ["svg", "abc" ]

-In most cases, it will be enough to just change:
-
-[mediaTypes]
-[mediaTypes."my/custom-mediatype"]
-suffix = "txt"

-To:
-
-[mediaTypes]
-[mediaTypes."my/custom-mediatype"]
-suffixes = ["txt"]
-
-Note that you can still get the Media Type's suffix from a template: {{ $mediaType.Suffix }}. But this will now map to the MIME type filename.
