3.4 Compatibility Notes has an example of a command that doesn't work, but it does

XMLWordPrintableJSON

      Description

      https://docs.mongodb.com/manual/release-notes/3.4-compatibility/#stricter-validation-of-collection-and-index-specifications says
      > For example, the following operation is no longer valid:

      db.createCollection( "myCappedCollection", { capped: true,  size: 5242880 } )

      However, this command works fine on my 3.4.16 node

      $ mongo --port 27018
MongoDB shell version v3.4.16
connecting to: mongodb://127.0.0.1:27018/
MongoDB server version: 3.4.16
Server has startup warnings:

shard01:PRIMARY> db.createCollection( "myCappedCollection", { capped: true,  size: 5242880 } )
{ "ok" : 1 }

      It also matches the spec in the same docs https://docs.mongodb.com/manual/reference/method/db.createCollection/#db.createCollection

      Can we change this example in the docs? It's not clear if there's something specific we want to demonstrate, but you have to specify valid options, so this no longer works:

      db.createCollection( "myCappedCollection", { customoption: true} )
