Probably that the value is illegal, either structurally or because it
would be a duplicate.

line 83: <a name="01">1</a>
line 96: <a name="02">2</a>
line 109: <a name="03">3</a>
line 112: <a name="04">4</a>

<td class="list">
 <a name="04">4</a>
</td>

Something wrong here?

I already replied privately.
HTML 3.2 had <a name="xx">.
HTML 4 added <any-element id="xx">,
and the recommended maximise-your-interoperability practice
for <a> is to copy <a name="xx" id="xx">.
(If an <a> has both name= and id= they must have the same
value, but having both at the same time is intended.)
Tidy wants to help copy the name= to name= AND id=
BUT an id= attribute value must start with a letter.
<a name="01" id="01"> would not be legal.
So Tidy won't do it.  Changing to <a name="N01"> would
make Tidy happy.
