i hope this issue can be solved in the next release.
i use the code editor, but i am sometimes too lazy to type the entire code out so i resort to these quicktags.
the 'link' quicktag generates a <a>. with the href attribute, but that is all to it. for it to be validated xhtml strict 1.0, it has to include a title attribute as well.
i hope in the next version, this is fixed.
