I'm confused - Element can map to xsd:any - whether Axis does it properly
or not is something different - but its possible, so why can't Element be
used in place of AnyContentType?  Not sure about the performance gain since
the minute anyone wants to do something with a MessageElement it will be
convert into a DOM, right?

Please respond to

Subject:    Re: AnyContentType

The purpose of the AnyContentType is to have an interface in common for all

types that contain an xsd:any element definition, so that utilities can
assume the availability of the get_any and set_any operations without
knowing the actual type. There is no type or construct in wsdl that maps to

Element as far as I know, and the fact that xsd:any elements do not get
deserialized into DOM Elements automatically  (but instead MessageElements)

can be a big performance gain.
