    That doesn't look ambiguous at all. If it's wrong (as suggested by the example, and the XHTML 1.0 and 1.1 DTDs), why has it never been fixed? I mean, that is a major technical error.

  Checking the same page, you can see the following for TBODY:

  <!ELEMENT TBODY    O O (TR)+           -- table body -->
  
  Start tag: optional, End tag: optional

  That would appear to mean, if I don't read it wrongly, that you can drop explicit mention of TBODY, so that embedded TR tags are in an implied TBODY, if you don't mention one.

    I thought that XHTML 1.0's reliance on the HTML 4.0 spec was a problem here, but C.11. #2 seems to address this specifically:

    User agents that access XHTML documents served as Internet media types text/xml, application/xml, or application/xhtml+xml can also use the XML DOM. Elements and attributes will be returned in lower-case. Also, some XHTML elements may or may not appear in the object tree because they are optional in the content model (e.g. the tbody element [emphasis added] within table). This occur

  It's a bug in the spec. (And the bug is not present in xhtml's dtd.)
