XML namespace

SVG

Scalable Vector Graphics. Required for a standalone .svg file to render as an image.

xmlns="http://www.w3.org/2000/svg"

SVG is real XML, which is why an SVG file can be validated, diffed and searched with XML tooling. A standalone SVG file must declare this namespace on its root element or browsers will treat it as unknown markup and render nothing.

Inline SVG inside HTML is the exception: the HTML parser assigns the namespace implicitly, so hand-written inline SVG often omits the declaration and still works.

URI: http://www.w3.org/2000/svg
Prefix: Usually the default namespace
Elements: svgpathgrectcircledefsusetext

Specification: SVG 2
