Why the two layers of <a> even if it passes $ validate http://en.wikipedia.org/wiki/Oaxtepec *** Errors validating Oaxtepec: *** Error at line 2, character 33: there is no attribute "class" Error at line 152, character 10: end tag for "ul" which is not finished Error at line 177, character 10: end tag for "ul" which is not finished
Why the </a> halfway through the first pair of Coordinates: 18°54′N 98°58′W / 18.9°N 98.967°W / 18.9; -98.967
Why does it look fine in some browsers but ah-ha caught you in emacs-w3m?
Could it be that Firefox and Chromium are fooled into thinking that the outer <a id...> which lasts through the whole six coordinates should render as a clickable link... which it apparently does even with stylesheets off. Only emacs-w3m renders it right, revealing the badly written HTML!
