Hi Vincent, I try to make the xhtmlparser work for the link. I have see the test case links.test in xwiki-core-rendering. I have some questions. 1) the xhtmlparser don't handle the rel attribute. Because wikimodel don't pass the information in xhtmlparser. see http://code.google.com/p/wikimodel/issues/detail?id=47. When this is fixed, I think rel can works. 2) The output of <a href="mailto:john@doe.com">mailto:john@doe.com</a> should be [[mailto:john@doe.com>mailto:john@doe.com]] but not [[mailto:john@doe.com]]. We should not remove the label information of mailto. Consider if the input is <a href="mailto:john@doe.com">Contact me</a>, the output should be [[mailto:john@doe.com>Contact me]] -- Thanks Wang Ning
