The problem I have with XML Schema and XHTML is with xml editors
(software, not people). Say someone wants to create an FAQ. It must
contain a question and an answer, like:
<div class="faq">
<div class="question">
<p>This is a question p1</p>
<p>p2</p>
</div>
<div class="answer">
<ol>
<li>some answer part 1</li>
<li>some answer part 2</li>
</ol>
</div>
</div>
there is no way to validate this with XML Schema. It is also why we use
XML instead of XHTML in our editor (Xopus).
I wish there was a good browser based, cross platform XML WYSIWYG editor
that uses RNG... - So I could use XHTML but keep it /valid/. As it
stands today, Xopus is the best choice. Anybody know of something that
competes?
