Thansk for your patience. I'll have to be even shorter tonight...

I see three solutions to implement a Html module:
  - pretend html is a xml dialect (xhtml is), and use Jordi's parser.=20
    It should be about 20 lines long. See the Guide module for an example.
  - pretend html is a sgml dialect, and use the sgml module for that. It
    will work if all html pages begin with a prolog stating the dtd. It
    should be the case, isn't it ?
    Then you have to list all tags in the relevant lists around line 400 of
    Sgml.pm. Just add a "    } elsif ($prolog =3D~ /html/i) {" block, and
    do the same than for other DTDs.
  - recognize html is uniq. You have to implement a whole new module in that
    case. You may well want to check how we did it for the sgml and xml
    modules. The best may be to translate a file with both of them, or so.

I'm not fond of this because if the translator wants/have to reordonate the
links, you'll have trouble. Check the gettext info file, in the section
explaining what "%2$s" is good for. It's not impossible, but you have to
deal with it.

Then, that's an argument of pretending that html is xml or sgml and not
reimplement any specif po4a module :)


Ok, I'm sorry, this mail really should be longer, but I'm out of time, man.
