Should remove the `xmlns:xlink` entirely, and replace `xlink:href` to `xlinkHref` about react-magic

[osdiab]

xmlnsXlink is now supported in the React docs, so it probably shouldn't be eliminated. https://facebook.github.io/react/docs/dom-elements.html

Probably a better option is just to handle namespaced attributes by camelCasing them and eliminating the colon, since that's invalid JSX.

It's used within <svg>. Unsure how it should be treated. Support for xlinkHref exists in jsx.

Is that actually HTML? <use> isn't a HTML tag.
