[quote user="iwpg"]The Frameset DTD requires there to be a frameset.[/quote] Yes, that is the WTF. A page with the XHTML 1.0 Frameset doctype isn't even supposed to have a body element! There should be no content on a page with such a doctype, only frames that contain content! <!DOCTYPE ...Frameset...><html xlmns="..."> <head> <title>...</title> </head> <frameset> <frame ... /> <frame ... /> </frameset></html>
