Replace the Epoz HTML editor by the FCKeditor HTML editor.
http://www.fckeditor.net/
FCKeditor produces XHTML, and moreover semantical XHTML, while Epoz produces
HTML 4.x being anything but semantic.
Using Epoz conflicts with CPS accessibility.
Example of XHTML code produced by FCKeditor:
This is some <strong>sample text</strong>. You are using <a
href="http://www.fckeditor.net/">FCKeditor</a>.<br/><br/>Is it <span
style="font-weight: bold;">XHTML</span>?<br/><br style="text-decoration:
underline;"/><span style="text-decoration: underline;">Poet</span><br type="_moz"/>
About Kupu which is another HTML editor:
FCKeditor could be a replacement (or an option) for Epoz, with just a few hours
coding needed. Kupu integration in CPS is something we should think about harder
before coding.
