Formal Metadata

Formal Metadata
TitleValidity error: table body before table heading
DescriptionAn XHTML file that is well-formed but not valid because the tbody element appears before the thead element in the table instead of after it. It cannot be predicted how assistive technology responds to this; possibly, the table heading is still read before the content of the table.
