- Added new subsection 9.6.2 The 'path-length' property with:
     - CSS property definition table (`none | <number [0,∞]`>, initial value `none`, applies to shapes and `textPath`, not inherited, not animatable).
     - Prose describing the property's effect on 'distance-along-a-path' calculations ('text-on-path' layout, motion animation, stroke dash operations).
     - Statement that `pathLength` is a presentation attribute for `path-length`.
     - Note referencing the CSS WG resolution.
