|
96
|
|
|
97 Содержимое для сложного узла. Порядок не важен. Дочерними элементами могут быть
|
|
|
98 только C<IMPL::DOM::Schema::ComplexNode> и C<IMPL::DOM::Schema::SimpleNode>.
|
|
|
99
|
|
|
100 При проверке данного правила, проверяются имеющиеся элементы на соответсие схемы
|
|
|
101 и количества встречаемости, после чего проверяются количественные ограничения
|
|
|
102 для несуществующих элементов.
