Ours doesn't. It recognizes some tags as a place to break sentences
for natural language processing, and it looks for the first undecorated
text in the document to use as a summary. It also saves text from
inside an <a> tag to index with the referenced document (no, Google
didn't do it first).

But it doesn't care whether <title> has an image, or which kind of
sentence-breaking tag is used (<p>, <blockquote>, <td>, ...).

Hmm, the "strict" variant makes looking for undecorated text
more difficult. I doubt that we'll interpret a stylesheets in 
order to index text. So anbody who wants to use "strict" had
better be ready to put in "description" meta tags.
