Completion in svg file proposes many duplicates

[fbricon]

Editing an svg file like this one causes completion to return many duplicate items:

<?xml version="1.0" standalone="no" ?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" "http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd">
<svg xmlns="http://www.w3.org/2000/svg">
    <animate attributeName="foo">
        <
    </animate>
</svg>
