Опробеливание Яндекса
Что происходит при одиночных закрывающих тегах, которые дают crop?
table td
ol li
</li><li>
<select><option>
Атрибуты alt и title в разных тегов
<noindex> до разбора проходит или после?

HTML коварен, потому что в нём много тегов и Яндекс считает нормальным придавать этим тегам разный смысл при разборе документов.
Разные теги привносят как разный семантический смысл, так и просто портят слова (склеивают, обрезают предложения, пропускают смешение алфавитов и т.п.).
Поэтому нам нужна такая табличка, чтобы быть настороже и помнить. Мы не должны забывать. И тогда, однажды.

Описание полей
- tag – открывающий и закрывающий теги
- replace – результат удаления тега или пары тегов (когда crop=1)
- passage – разделитель пассажей
- space – пробел
- empty – пустая строка
- crop – признак вырезания всего внутри пары тегов. Но это не точно
