DELETE /openapi/memorylake/api/v1/drives/items/{item_id}/xattrs?key={comma-separated-keys}
Removes one or more extended attribute keys from a Library file or folder. Only the keys you list are removed; any other xattrs on the item stay where they are.
This is irreversible. The listed xattr values are gone after the call. The item itself is not affected — only the listed metadata keys.
System-reserved xattr keys cannot be deleted; including them in the key list is rejected. The system root folders (My Space, WPS Space, Lark Space) refuse xattr deletion entirely and return 403.
