List of file extensions (including the leading dot) like '.x3dv'. Must be non-empty, that is: at least one extension must be provided here.

If the model filenames contains multiple extensions, you can specify them here, e.g. ".x3dv.gz" is a valid extension on this list. It is common to pack X3D files in gzip and use ".x3dv.gz" extension, so we handle it here.

It's your responsibility to make sure that all extensions here map to one of the MIME types specified in MimeTypes.
