When using SVG, you may receive the error “Namespace prefix xlink for href on image is not defined”.
This occurs because the xlink:href indicating the SVG link is not properly defined.
As a workaround, add the xmlns:xlink attribute to the SVG tag as follows
<svg xmlns:xlink="http://www.w3.org/1999/xlink"> ... </svg>
This will correctly define the xlink namespace and eliminate the error.
