Trivial Description
When using a Servlet 2.4 compliant web.xml, warnings are shown for some elements that are valid according to the spec. This is purely a cosmetic issue, with no loss of function whatsoever. It does create some confusion when users see this message (e.g. http://www.mail-archive.com/users@myfaces.apache.org/msg28066.html), so it might be worth fixing at some time.
WARN [WebXmlParser] Ignored element 'dispatcher' as child of 'filter-mapping'.
