Hi all, I have been embedding svg inside html macro like this: {{html}} <svg ...> ... </svg> {{/html}} and usually I can convert the resulting page to PDF without any problem. However if I use *xmln:href* in the svg, the PDF converter throws an error and renders a blank PDF. Here's an example svg: https://jsfiddle.net/9dt5guab/1/ Here's the stack trace: ERROR o.a.f.a.FOUserAgent - SVG graphic could not be built. Reason: org.apache.batik.bridge.BridgeException: file:/opt/web/base/./:-1 The attribute "xlink:href" of the element <use> is required org.apache.batik.bridge.BridgeException: file:/opt/web/base/./:-1

Any help?
