scheme 属性は、 content 属性の値の型を明示するために使います。型名は機械が読めるものではなく、人間が読むということで、きちんと定義されてはいません。meta 要素にも scheme 属性が (たぶん HTML からこぴってそのまま) あるみたいだけど、 UA は対応してないぽ、って書いてある。HTMLMetaElement.scheme 属性が対応します。[29] IW:HTML4:"struct/global.html#idx-scheme" の例で、 HTML 4.0 では Month-Date-Year を挙げていましたが、 HTML 4.01 で minor typo として Month-Day-Year に修正されました。
参考: IW:HTML4:"appendix/changes.html#h-A.1.3"

は、 schema.PREFIX によるURLと接頭辞との関連付けの仕組み
(DCMI が <meta name> に関して提案していたもの)
を scheme 属性値にも適用しているようです。

scheme 属性値を定義する HTML メタ情報プロファイル[55] HTML 4 によれば scheme 属性値の解釈は使用している
HTMLメタ情報プロファイルと name
属性値によって決まります。

profile 属性が指定されていない状態で使える
scheme 属性値はありません (少なくても HTML 4

実際に scheme を使った例が仕様書に載っています。

>>58 の scheme 属性値が使えると解釈することもできると思われます。
