Hi Anika,

Great work so far on bring dokwiki's xhtml into line. :-)

I'd be inclined to go further to prevent non-unique ids.

e.g.

hd1_2_ways_to_do_it_better
hd2_1st_way
hd3_2nd_way
hd4_3_more_ways_to_do_it_better
hd5_1st_way
hd6_2nd_way
...

Perhaps even allowing the renderer to have a prefix specified, to allow 
web pages with multiple wiki pages (e.g. sidebars or includes) to avoid 
id collisions.

Cheers,

Chris
