lahmatiy has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-values] Definition of 2D Positioning: the <position> type ==
The latest version of CSS Backgrounds and Borders Module Level 3 has changed definition of `<bg-layer>` and `<final-bg-layer>` to use `<bg-position>` instead of `<position>`. I did a little research into the difference and found that CSS Values and Units Module Level 4 has its own syntax of `<position>` with notes:

> Note: The background-position property also accepts a three-value syntax. This has been disallowed generically because it creates parsing ambiguities when combined with other length or percentage components in a property value.

It's good to know. But there are a couple of problems:

- CSS Values and Units Module Level 4 (WD) – doesn't reflect changes about `<position>` in `Changes` section
- CSS Values and Units Module Level 3 (CR) – still refers to CSS Backgrounds and Borders Module Level 3 with no notes about the difference

I believe it should fixed in one way or another to be less confused: add a notes to `<position>` section and an entry to Changes section to L3, or add an entry to Changes section in L4.
