The Precomposed Inline-level Display Values section defines the following <display-legacy> keywords:
inline-block: Behaves asinline flow-root.inline-table: Behaves asinline table.inline-flex: Behaves asinline flex.inline-grid: Behaves asinline grid.
However, <display-legacy> allows a 5th possibility: inline-list-item.
According to the summary table, it should be
inline-list-item: Behaves aslist-item inline flow.
Or, to maintain a similarity among all these definitions, the equivalent
inline-list-item: Behaves asinline list-item.
Or maybe inline-list-item should be dropped. All the other precomposed inline-level values are inline- followed by an inner display type, and exist for legacy reasons. But list-item is not an inner display type, and is a new addition.
I don't think anyone has implemented inline-list-item yet - it's just specified over in Lists, as a useful feature. If so, we should just drop it, and let people write inline list-item if they want.
The CSS Working Group just discussed Publishing an updated WD of css-align and css-display, and agreed to the following resolutions:
RESOLVED: Publish an updated WD of css-alignThe full IRC log of that discussion
<dael> Topic: Publishing an updated WD of css-align and css-display
<Rossen_> t- ?? wow :)
<dael> astearns: align it's an updated WD
<dael> fantasai: Yep. We wanted dbaron approval on that since a lot of the issues were filed by him. If he's okay publishing now or wants more time to look.
<dael> dbaron: I think there's more work to do, but I wouldn't obj to a new WD. I went through the commentor response required, well, all but 3. THere were 4 I marked as not satisfied.
<dael> fantasai: Great. publish an update and keep working
<ChrisL> that is an auto-publish, right?
<dael> astearns: Obj to updated WD of css align?
<fantasai> ChrisL, yes
<dael> RESOLVED: Publish an updated WD of css-align
<dael> astearns: Second is also updated WD of css-display. Looked like fewer issues.
<dael> fantasai: Fewer, but quite a few. We could do 1495 quickly before publish. We should do an update and then keep working.

we confused the bot - the actual minutes on this issue are
fantasai: Suggestion was it's a little different then some of the others and do we really need this one. It might be worth dropping that unless someone has impl and wants to keep it.
astearns: Anyone know if inline-list-item has been imp?
Rossen_: I don't believe we are.
astearns: Obj to dropping inline-list-item?
fantasai: No hits in Mozilla's codebase
RESOLVED: Drop inline-list-item
We need to be kinder with the bot, or it might try to drown itself ;-)
