Is license AGPL-3.0-or-later or AGPL-3.0?

[eNV25]

spdx has two different IDs for AGPLv3:

https://spdx.org/licenses/AGPL-3.0.html

https://spdx.org/licenses/AGPL-3.0-or-later.html

The way I interpret it is that it's v3 or any later version (since afaik there's no statement to the contrary).

	14. Revised Versions of this License.
	The Free Software Foundation may publish revised and/or new versions of
	the GNU Affero General Public License from time to time. Such new versions
	will be similar in spirit to the present version, but may differ in detail to
	address new problems or concerns.
	Each version is given a distinguishing version number. If the
	Program specifies that a certain numbered version of the GNU Affero General
	Public License "or any later version" applies to it, you have the
	option of following the terms and conditions either of that numbered
	version or of any later version published by the Free Software
	Foundation. If the Program does not specify a version number of the
	GNU Affero General Public License, you may choose any version ever published
	by the Free Software Foundation.
	If the Program specifies that a proxy can decide which future
	versions of the GNU Affero General Public License can be used, that proxy's
	public statement of acceptance of a version permanently authorizes you
	to choose that version for the Program.
	Later license versions may give you additional or different
	permissions. However, no additional obligations are imposed on any
	author or copyright holder as a result of your choosing to follow a
	later version.
