It is a container for subproperties (or a submicroformat) , in hReview,
similar to how "adr" is a container for subproperties.

What help were you expecting? Perhaps I can add it either in the
specification or in a tutorial / authoring page.

Could you provide a specific explanation of which example is inconsistent
with which statement in the prose of the specification?
Or even if there is no specific inconsistency, if you could elaborate on how
the current prose/examples *seemed* inconsistent, even that is worth fixing.
The examples below are consistent with the specification quoted above as

This example uses the feature of the definition quoted:
Encapsulated microformats (e.g. hCard and hCalendar events for now)
may be set on the item itself (e.g. class="item vcard").
> * <div class="item vcard">
> <div class="fn org summary">Cafe Borrone</div>

> <span class="tel">+1-650-327-0830</span>;

As does this one.

This example shows an item which is a product (not a business nor an event),
and thus uses "url" and "fn" properties *inside* the item per the portion of
specification above quoted:
when using item info subproperties ("fn", "url", "photo"), they MUST
be nested inside the item element.
> * <div class="item">
> <a lang="zh" class="url fn"
> Ying Xiong (<span lang="en">HERO</span>)
As does this one.
