<h4>Version History</h4>
<ul>
<li>1.3: Thanks to a tipp now the link-path to the stylesheets is correct, sorry for the inconvenience</li>
<li>1.2: Leading whitespace isn’t stripped anymore (indents as well as newlines), when there’s no title the title-div is not being generated anymore</li>
<li>1.1: Solved the issue with single-quotes being changed to typographical quotes</li>
</ul>
<h4>Known Issues</h4>
While the plugin is basically XHTML 1.0 Strict compliant there’s just no way of getting the offset-based line-numbering to display without inadequate (ab)use of javascript and css hacks, so be warned that IF you use the line-number offset, your documents will NOT validate because of the forbidden <code>start=</code>-attribute for the <code><ol></code>!
