NO!!!!!! Do NOT add a field element to the bean metadata.

if you want to do field injection then these should be included in
the BeanInfo abstract as properties.

i.e. the property has the same name as the field and the
get/set operations work on the field joinpoints.
But only if the property has no relevant getter/setter.

I'd suggest that field injection should be enabled explicitly
by specifying some sort of access rule on the bean element/BeanMetaData
like JAXB does.
