At present, the HTML parser that cleans up data entered appears to only work for HTML 4 standards and not XHTML. Whilst this may sound petty, expanding the parser to suit the latter means that bad habits such as <br/> are not rejected, it also gives the ability for inline SVG to be possible, so projects need not have to have image files for diagrams if they know that browser compatibility is a non-issue. In addition to this, any other crazy embeddable XML formats (like MathML) would also be possible.
