On Commons the widely-used Template:Information contains code for machine-readibility. It takes the parameters and puts them in urlencoded form to the title attribute of a hidden <span>, so scripts can easily read them (at least I guess that's what it's for, the "machine-readibility code" is not documented well). Now the parameters of Template:Information can get quite long. It seems that if the urlencoded string is longer than 33,xxx characters, it breaks. See for example <http://commons.wikimedia.org/w/index.php?title=File:World_homosexuality_laws.svg&oldid=19428970> (at the bottom of the description). The problem is not in the template or in the source of that specific file. It happens to all very long attributes. The whole <span> is corrupted in the HTML source code. I guess, the problem is in the parser or in tidy. Does anybody know, what's the exact reason and how to fix it? Marcus Buck User:Slomox
