Incorrect HTML on PHP documentation webpages

The function definition pages in the documentation all incorrectly nest <dd> elements inside <dt> elements, which does not follow the HTML spec. This seems to cause no problems on browsers, but I noted the problem when developing an HTML parser. It would be good to get it right. May I take the opportunity to thank you for a fantastic resource. The documentation is concise, and well laid out; the user notes are particularly helpful when debugging problems. Thanks, Ian Back
