+Actually, there's a way to embed SVG into MarkDown sources using the [data: URI scheme][rfc2397], [like this](data:image/svg+xml;base64,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).

+This would be really neat, including the svg with an img tag limits the functionality because then any text in the svg is not parsed for [[WikiLinks|ikiwiki/wikilink]] or similar.  You could do some neat things like a timeline or a family tree where you would want mixed text and graphic elements by mixing markdown and svg on the same page.
