Схема планировщика задач

Схема планировщика задач определяет допустимый XML-код, используемый для регистрации задач в службе планировщика задач. Разработчики могут создавать собственные XML-файлы, проверять его на соответствие этой схеме и регистрировать задачи с помощью метода ITaskFolder::RegisterTask .

Типы и элементы схемы планировщика задач по отдельности описаны в следующих разделах.

Вся схема планировщика задач определяется следующим XSD-файлом.
