You can automate much of it with server side scripting...

<?php

global $faq;
$faq = array();
$faq['h_num'] = 0;
$faq['q_num'] = 1;
}

function faq_heading ($h)
{
global $faq;
$faq['h_num']++;
$faq[] = array(
'n'=>$faq['h_num'],
'heading'=>$h
);
$faq['q_num'] = 1;
}

function faq_question ($q, $a)
{
global $faq;
$faq[] = array(
'n'=>($faq['h_num'] . '.' . $faq['q_num']),
'question'=>$q,
'answer'=>$a
);
$faq['q_num']++;
}

function faq_finalise_index ()
{
global $faq;

$out = "<div id=\"q_idx\">\n"
. " <h1>Frequently Asked Questions</h1>\n";

for ($i=0; isset($faq[$i]); $i++)
{
$f = $faq[$i];

if (isset($f['heading']))
$out .= " <div>\n"
