What is "Kind" in IDS?

[registereduser]

When fill IDS, I read:

Kind - Enter the Kind code of the patent number if known. WIPO Standard ST. 16 codes (kind codes) include a letter, and in many cases a number, used to distinguish the kind of patent document (e.g., publication of an application for a utility patent (patent application publication), patent, plant patent application publication, plant patent, or design patent) and the level of publication (e.g., first publication, second publication, or corrected publication).
