XmlSchemaGroup クラス

複合型から参照される schema レベルのグループを定義するクラス。要素宣言セットをグループ化し、グループとして複合型定義に組み込むことができるようにします。W3C (World Wide Web Consortium) group 要素を表します。

この型のすべてのメンバの一覧については、XmlSchemaGroup メンバ を参照してください。

スレッドセーフ

この型の public static (Visual Basicでは Shared) のすべてのメンバは、マルチスレッド操作で安全に使用できます。インスタンスのメンバの場合は、スレッドセーフであるとは限りません。
