Multiple value tags are Xmp tags of type "XmpAlt", "XmpBag", "XmpSeq" or "LangAlt", or Iptc tags marked as Repeatable (which can be of any Iptc type). There are no multiple value Exif tags.

The Exiv2 Tag Reference can be found at http://exiv2.org/metadata.html

Parameters:

this	An instance of [class@GExiv2.Metadata]
tag	An Exiv2 tag

Returns:
