karlcow has just created a new issue for https://github.com/w3c/svgwg: == refX/refY keyword forms unimplemented and no WPT tests == The [marker element](https://w3c.github.io/svgwg/svg2-draft/single-page.html#painting-MarkerElement) has for attributes [refX](https://w3c.github.io/svgwg/svg2-draft/single-page.html#painting-MarkerElementRefXAttribute) and refY. The specs defines values * refX (left | center | right) * refY (top | center | bottom) alongside `<length-percentage>` | `<number>`. On the [London F2F - August 2014](https://www.w3.org/2014/08/26-svg-minutes.html#item07), it was decided to add the keywords to the [symbol element](https://w3c.github.io/svgwg/svg2-draft/single-page.html#struct-SymbolElement) too. A. There are no WPT tests about RefX/RefY on `symbol` B. There are no WPT tests about the keyword values (left|center|right, top|center|bottom) on both `marker` and `symbol`. C. There are **no implementations at all in browsers** of these keywords. (12 yearsis t) D. The SVG2 IDL doesn't expose them either or the prose needs to be aligned with rect/ellipse aka "reflect the computed values". Keyword resolves to a length at parse time; SVGAnimatedLength exposes only the resolved length.
