canvg fails on svg with xmlns

Question

I am using canvg to render the following svg to the canvas however it fails. I am not sure why

<svg class="circularReferenceSVG" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
            <marker xmlns="http://www.w3.org/2000/svg" id="triangle" viewBox="0 0 10 10" refX="0" refY="5" markerUnits="strokeWidth" markerWidth="4" markerHeight="4" orient="auto">
                <path d="M 0 0 L 10 5 L 0 10 z" fill="#000000"></path>
            </marker>
        </svg>

My guess is that it has to do something with xmlns. I could not find on the canvg webpage anything about it. Any help will be appreciated.

Here is the screenshot of where the canvg seems to fail Here point and angle is undefined

That SVG does not contain any elements that will display. i.e. it is blank. So if you render it on canvas it will be blank there too. — Robert Longson, Apr 07 '17 at 21:30
By 'fails' I mean that canvg throws an error. Even if the svg markup does not draw anything, still it should be able to parse it, however it does not — Gagan, Apr 10 '17 at 13:21
@RobertLongson I have updated the question with the screenshot — Gagan, Apr 10 '17 at 13:53
