I can't reproduce that. Can you post an example URL? I think there must
be another error in your markup. The following simple code snippet does
validate as HTML 4.01 Strict, XHTML 1.0 Strict and XHTML 1.1:

<table>
<thead>
<tr><th>test</th></tr>
</thead>
<tbody>
<tr><td>content</td></tr>
</tbody>
</table>

This is correct.

This statement is wrong or at least misleading. Given the DTD and the
actual validation results, I would say it this way:

By default all rows are put into an implicit 'tbody', so there's no need
to declare it. But if you use any of the row group elements 'tbody',
'thead' or 'tfoot', then every row must be contained in an explicitly
declared row group.
