href attributes without the xlink namespace are not recognised
Summary:
If an attribute is not properly namespaced, Inkscape will ignore it. Take this example: https://developer.mozilla.org/en-US/docs/Web/SVG/Element/use
It's something I've had issues with for many years. I work a lot with SVG for web applications and often use Inkscape to generate PDF/PNG files on the server from files generated on the web. I always need to run over the SVG files and do some tweaks. Adding the xlink: prefix is the most common one.
Steps to reproduce:
Save the following SVG example to a file and open it in Inkscape:
<svg viewBox="0 0 30 10" xmlns="http://www.w3.org/2000/svg">
<circle id="myCircle" cx="5" cy="5" r="4" stroke="blue" />
<use href="#myCircle" x="10" fill="blue" />
<use href="#myCircle" x="20" fill="white" stroke="red" />
</svg>
What happened?
The use elements should show, but they don't.
What should have happened?
The use elements should be rendered.
