You should include the following attributes into to the svg tag, otherwise it will not render correctly in browsers.

xmlns="http://www.w3.org/2000/svg xmlns:xlink="http://www.w3.org/1999/xlink version="1.2"

Most recent browsers support HTML5, which allows SVG with implicit SVG and XLink namespaces. Not that I suggest you don't use namespaces in standalone SVG, as that is still required.
