ordered sublist

(How) Is it possible to write HTML-code that results in the following
ordered list (without 'hardcoding' the numbers) ?

1. First Item
    1.1. First Subitem of First Item
    1.2. Second Subitem of First Item
    1.3. Third Subitem of First Item
2. Second Item
    2.1. First SubItem of First Item
    2.2. Second Subitem of Second Item

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I'd like to know too...

I'm afraid, you can't ;-)
You can't in HTML, to be sure. The closest solution would use two nested <OL> sets, and look like this:

<LI>First Item
    <LI>First Subitem of First Item
    <LI>Second Subitem of First Item
    <LI>Third Subitem of First Item
<LI>Second Item
    <LI>First SubItem of First Item
    <LI>Second Subitem of Second Item

Maybe we could cobble a JavaScript solution? It'd be ugly, but it would work --

var mc = 0;    // main counter
var sc = 0;    // sub counter
function mcount() { mc++; document.write(mc+". "); }
function scount() { sc++; document.write(mc+"."+sc+". "); }

<DT><SCRIPT LANGUAGE="JavaScript">mcount()</SCRIPT>First Item
    <DD><SCRIPT LANGUAGE="JavaScript">scount()</SCRIPT>First Subitem of First Item
    <DD><SCRIPT LANGUAGE="JavaScript">scount()</SCRIPT>Second Subitem of First Item
    <DD><SCRIPT LANGUAGE="JavaScript">scount()</SCRIPT>Third Subitem of First Item
<DT><SCRIPT LANGUAGE="JavaScript">mcount()</SCRIPT>Second Item
    <DD><SCRIPT LANGUAGE="JavaScript">scount()</SCRIPT>First SubItem of First Item
    <DD><SCRIPT LANGUAGE="JavaScript">scount()</SCRIPT>Second Subitem of Second Item

Funny idea mblase...pretty close to the request...
Congrats !(didn't think of that way)
Actually, that doesn't *quite* do what Ann wanted. Here's the line to modify:

function mcount() { mc++; sc=0; document.write(mc+". "); }

Before it counted 1, 1.1, 1.2, 2, 2.3, 2.4... instead of 2, 2.1, 2.2, as desired. This will correct that.
Oh, and if you want to make the code a little cleaner, you should be able to eliminate LANGUAGE="JavaScript" from all the <SCRIPT> tags, since all browsers should default to JavaScript as the scripting language to use.
