xi:include in svg

[pg83]

I have following svg, generated by gtk toolkit, for symbolic svg icons:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg version="1.1"
     xmlns="http://www.w3.org/2000/svg"
     xmlns:xi="http://www.w3.org/2001/XInclude"
     width="16"
     height="16">
  <style type="text/css">
    rect,circle,path {
      fill: rgb(0,255,0) !important;
    }
    .warning {
      fill: rgb(255,0,0) !important;
    }
    .error {
      fill: rgb(0,255,0) !important;
    }
    .success {
      fill: rgb(0,255,0) !important;
    }
  </style>

</svg>

Actually I have some questions about this svg:

1. Is it svg at all? It is rendered correctly by librsvg. (I am not an expert in svg spec).
2. If it is svg, will you support it in svgren? For now I have some ugly (regexp) workarounds for such svgs.

Hi, thanks for report!

XInclude XML extension is not supported by svgren at the moment, but perhaps it would be good to add it in the future.
SVG spec doesn't say anything about XInclude so, strictly speaking it is not an pure SVG, but XInclude is an XML extension, while SVG is based on XML, so, perhaps this file makes sense.

I'm not sure when I could implement it in svgren, but let's keep this issue open for this.
