"HTML5" mode determination is based on the HTML 5 draft of 2008-01-22 plus this correction.
"IE7" mode determination is based on this description.
The source data is 434 HTTP URIs from the Alexa Top 500 Sites (excluding the repeated country-specific Google and EBay sites), downloaded on 2008-02-27.
The 'doctype' of a page was approximated as the first string matching the regular expression
(?i)<!doctype[^>]*?>. (This under-estimates the number of quirks-mode pages, since it
ignores any content preceding the doctype). All whitespace was then collapsed
into single space characters, and the strings lowercased.
