OWL documents do not follow HTML compatibility guidelines


The current versions of the OWL 2 documents are served with the content type text/html and also explicitly set this with a <meta> tag. However they contain XHTML that does not follow the HTML compatibility guidelines for XHTML [1].
For example they start with the <?xml?> declaration, don't use spaces in front of /> and most importantly: they use the minimised form of empty elements. This leads to one very visible bug in Opera: in the New Features and Rationale document from a certain section on [2] everything is rendered as monospaced text. This is because this section contains a <span class="name"/> which Opera correctly assumes to be just an opening tag because it parses the document as HTML and not as XHTML. I'm seeing this in Opera 9.64 on Linux.
A quick fix is just to remove this element as it doesn't do anything. Even better would be though if all documents would follow the compatibility guidelines. I can understand if this is too much work though. It seems like the documents are automatically converted from the wiki pages?
