Are you aware that XHTML 1.0 Appendix C  did *not* support that kind of 
flagging? On the contrary! 

Of course, for *end* tags, then XHTML 1.0 validation did of course 
catch such errors. But for  auto-generated elements, like <tbody>, 
then, as noted in the PolyglotRecommendationRationale, XHTML 1.0 
required *XML parsers* to adapt (which is directly opposed to the 
identical DOM principle):

You may also try to validate such a page:

<http://validator.w3.org/check?uri=data%3Aapplication%2Fxhtml%2Bxml%3Bcharset%3Dutf-8%3Bbase64%2CPCFET0NUWVBFIGh0bWwgUFVCTElDICItLy9XM0MvL0RURCBYSFRNTCAxLjAgU3RyaWN0Ly9FTiIgImh0dHA6Ly93d3cudzMub3JnL1RSL3hodG1sMS9EVEQveGh0bWwxLXN0cmljdC5kdGQiPjxodG1sIHhtbG5zPSJodHRwOi8vd3d3LnczLm9yZy8xOTk5L3hodG1sIiB4bWw6bGFuZz0iZW4iIGxhbmc9ImVuIj48aGVhZD48dGl0bGU%252BdGl0bGU8L3RpdGxlPjwvaGVhZD48Ym9keT4NCg0KPHRhYmxlPjx0cj48dGQ%252BYWJjPC90ZD48L3RyPjwvdGFibGU%252BDQoNCjwvYm9keT48L2h0bWw%252BDQo%253D&charset=%28detect+automatically%29&doctype=Inline&ss=1&group=0&user-agent=W3C_Validator%2F1.3>
