lgtm except for the wrong definition of <translation-value>

this is the wrong section, this is talking about deprecated syntax in the svg
transform attribute and confusingly uses a "<translation-value>" that's
different from the css meaning of <translation-value>.

css <translation-value> should have the signature
  "<percentage> | <length>"
and it's described here:
