@blink1073 How can I make enforce-label pass? I can't set labels on the PR by hand...

Ah, I'll still need to see that xlink:... gets correctly kept.

Ah, darnit. bleach apparently happily cleans out xlink:href to href, which will probably break embedded SVGs... mozilla/bleach#362

@blink1073 Right, this PR will allow a certain subset of SVG embedded into HTML.

The templates for actual image/svg+xml cells (e.g.

nbconvert/share/templates/lab/base.html.j2

Line 166 in a806744

{{ output.data['image/svg+xml'].encode("utf-8") | clean_html }}
) should use an XML-savvy cleaner since a image/svg+xml is not HTML to begin with.

This PR is nevertheless an improvement to the status quo... What do you think?
