Wasn't sure which forum to post this in, figured here was a safe start.

I'm just getting into the whole XHTML validation thing, having officially "certified" my search addon template tonight, (and after seeing the results, I'm going to go back and validate all the other pages I've built as addons for my site

).
One of the errors it gave was on my closing </form> tag for the search form.
Now, I admit, I'm self taught in all my HTML, PHP, Perl coding, actually took two semesters of C++ when I was in college, (forgotten more than I care to admit about C++, but it's helped me with my PHP and Perl coding), and as I was learning these languages, having closing tags was always reinforced.
So, why would the validator require me to remove the closing tag, stating that no form is open when there is indeed a form opened?
Anyways, if anyone could just give a brief synopsis of why this is now appropriate, where it once wasn't, I'd be greatly appreciative.

Thanks all.
