Question about section 8.2.4.6. Dereferencing; is the reference to $id incorrect? Should be $anchor?

I'm trying to update my validator to 2019-09 and looking for precise info about how to handle new keyword $anchor.

I searched for $ahcnor references in the 2019-09 spec that I have.

"When an implementation encounters the <#/$defs/single> schema, it resolves the "$id" URI reference against the current base URI to form https://example.net/root.json#item."

json-schema-spec/jsonschema-core.xml

Line 1712 in 30f3158

When an implementation encounters the <#/$defs/single> schema,

However the snippet above does not include an $id property at defs/single; it has an $anchor property.

Is that incorrect or have I misunderstood?

Yeah, that looks wrong. Probably something that slipped through the cracks when $anchor was split off of $id.

Prior to draft 2019-09, "$anchor": "item" from that example would have been "$id": "#item". In that form, the description makes sense. $anchor should behave exactly like an $id starting with a fragment did in previous drafts. The only difference is that the leading # is no longer used.
