Валидатор на статьях выдает предупреждения по следующим пунктам. Помогите исправить.
Warning: Consider using the h1 element as a top-level heading only (all h1 elements are treated as top-level headings by many screen readers and other tools).
From line 539, column 5; to line 539, column 8
↩ <h1>↩
---------------------------------------
Warning: The name attribute is obsolete. Consider putting an id attribute on the nearest container instead.
From line 624, column 9; to line 624, column 27
>↩ <a name="comments"></a>↩
---------------------------------------
Warning: Section lacks heading. Consider using h2-h6 elements to add identifying headings to all sections.
From line 495, column 13; to line 495, column 41
<section style="width:730px">↩↩
Ругается на отсутствие h1, устаревшего тега и отсутствие h2-h6. Где дописать, чтобы не ругался?
