default/help text

I want to put some help text in an editor instance that disappears on focus. So far I have:

    for (instance in CKEDITOR.instances) {
        var editor = CKEDITOR.instances[instance];
        editor.on('focus', function(event) {
            if (event.editor.getData() == "<p>" + ckeditor_default_text[event.editor.name] + "</p>\n") {
                event.editor.setData("");
                event.editor.focus();
            }
        });
        editor.on('blur', function(event) {
            if (event.editor.getData() == "") {
                event.editor.setData(ckeditor_default_text[event.editor.name]);
            }
        });
    }

which works but I don't like having to hard code "<p>" and and "</p>\n". Any tips for improvement?
