+### JSON SchemaのobjectでanyOfを使うとき
+JSON Schemaで、objectに対してanyOfを使う場合、anyOfの中でpropertiesを定義しないこと。  
+バリデーションが効かないため。（SchemaTypeもそのように作られており、objectのanyOf内のpropertiesは捨てられます）

+テキストhogeおよびfugaについて、片方を必須としつつ両方の指定もありうる場合:

+export const paramDef = {
+	type: 'object',
+	properties: {
+		hoge: { type: 'string', minLength: 1 },
+		fuga: { type: 'string', minLength: 1 },

 ### コネクションには`markRaw`せよ
 **Vueのコンポーネントのdataオプションとして**misskey.jsのコネクションを設定するとき、必ず`markRaw`でラップしてください。インスタンスが不必要にリアクティブ化されることで、misskey.js内の処理で不具合が発生するとともに、パフォーマンス上の問題にも繋がる。なお、Composition APIを使う場合はこの限りではない(リアクティブ化はマニュアルなため)。
