Current spec language: For a polyglot document, a table must explicitly have a tbody element surrounding groups of tr elements. HTML pasrsers insert the tbody element, but XML parsers do not, thus creating different DOMs. Correct: <table> <tbody> <tr>... Incorrect: <table> <tr>... Notes: Issue raised in mail sent by Sam Ruby[1]: There are two ways to address this: treat tables without explicit tbody's as non-conforming, or treat style rules that produce different results based on the existence of tbody elements to be non-conforming. As luck would have it, I had an opportunity to observe this exact discussion. DanC and PLH preferred it when tbody elements were included, TimBL preferred to not include tbody elements when they were not necessary. I didn't express an opinion in that venue, but I will say that while I don't currently routinely use tbody elements, I do think it would be better approach if this document were to suggest that they were required.
