[VE][html5] The a

The on-line guide to HTML 5 uses this example of an in-page link:
<a href="#tips">Visit the Useful Tips Section</a>

But when I use:
<tr><td><a href="#00">IDENTICAL : English = Espa&ntilde;ol</a><br></td></tr>

which seems to have the identical structure I get 


--------------------------------------------------------------------------------


Line 37, Column 22: The element a must not appear as a descendant of the a element.
<tr><td><a href="#00">IDENTICAL : English = Espa&ntilde;ol</a><br></td></tr>--------------------------------------------------------------------------------- and 21 others similarly as it is a line in the Contents table.

Error [html5]: ""
NOTE: Whenever possible, give the address of the document you were checking.

Sorry: it's in a file used for a Kindle publication so it's not on-line in that form.  The file is rather big (556 KB) but I could send you the first 50 lines, say, if that would be helpful.

Hope you can advise.
