Комментарии

Этот класс предназначен для упрощенной реализации простой объектной модели XML для использования в системе безопасности, а не для использования в качестве общей объектной модели XML. В этой документации предполагается базовое знание XML.

Простая объектная модель XML для элемента состоит из следующих частей:

• Тег — это имя элемента.

• Атрибуты представляют собой ноль или более пар атрибутов "имя-значение" в элементе .

• Дочерние элементы — это ноль или несколько элементов, вложенных в <tag> и </tag>.

Настоятельно рекомендуется использовать xml-представление на основе атрибутов для выражения элементов безопасности и их значений. Это означает, что свойства элемента выражаются в виде атрибутов, а значения свойств — в виде значений атрибутов. Избегайте вложения текста в тегах. Для любого <tag>text</tag> представления обычно доступно представление типа <tag value="text"/> . Использование этого xml-представления на основе атрибутов повышает удобочитаемость и позволяет легко переносить WMI результирующей XML-сериализации.

Имя атрибута должно быть на один символ или длиннее и не может быть null. Если используется представление значения на основе элементов, элементы с текстовой строкой null , представленные в форме; в <tag/> противном случае текст разделяется маркерами <tag> и </tag> . Обе формы можно сочетать с атрибутами, которые отображаются при их наличии.

Теги, атрибуты и текст элементов, если они присутствуют, всегда чувствительны к регистру. Xml-форма содержит кавычки и escape-адреса, где это необходимо. Строковые значения, включающие недопустимые символы для использования в XML, приводят к созданию ArgumentException. Эти правила применяются ко всем свойствам и методам.
