svg xmlns unrecognized attribute

[machty]

Making a note to expand upon this later; not sure what the userland fix is for something like this or what needs to be fixed upstream.

src/components/fpr/checkbox-icon.gts:20:9 - error TS2353: Object literal may only specify known properties, and 'xmlns' does not exist in type 'Partial<WithDataAttributes<SVGSVGElementAttributes>>'.

20         xmlns="http://www.w3.org/2000/svg"
           ~~~~~

@machty yes, this popped up as part of #880.

I started to think of it as a useful error in glint, since xmlns is only required on the outermost svg element of SVG documents, not when embedded in HTML:

Note: The xmlns attribute is only required on the outermost svg element of SVG documents, or inside HTML documents with XML serialization. It is unnecessary for inner svg elements or inside HTML documents with HTML serialization.

Nice, TIL: the html parser will already/automatically assume the SVG namespace is being used and hence xmlns is unnecessary.
