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

== [css-lists] Contradictory normative requirements for implicit 'list-item' counter? ==

> Unless the counter-increment property explicitly specifies a different increment for the list-item counter, it must be incremented by 1 on every list item, at the same time that counters are normally incremented.

but then later

> UAs and host languages should ensure that the list-item counter values reflect the underlying numeric value dictated by host language semantics when setting up list item styling in their UA style sheet and presentational hint style mappings.
> Not really sure how to word this requirement, but the following example is expected to work.

In particular consider cases like `<ol reversed>` or `<li value="">`. The host language [specifies](https://html.spec.whatwg.org/#ordinal-value) an algorithm for figuring out the "underlying numeric value". But that value decreases. This seems to contradict the above "must" that it be incremented by 1.
