You mean besides the xsd? :-)

I don't know how you would define something abstract.
The information you want comes from the BeanInfo
not the MetaData. The MetaData is just the key.

e.g. className + property name -> getBeanInfo(className).getProperty(name).getType();

It is even more complicated for parameters since then you
have to iterate to constructors and do a "fuzzy match"
to try to guess which constructor they mean.

The current logic is in the Configurator for matching joinpoints.

My guess would be that you would need to:
1) Implement the revisit() of the meta data such that
you have the metadata context after the BeanInfo has been
determined. a simple way to be to add a visitDescribed() path.

2) The ADVMD then asks its parent on the stack getClass();

which will for a property
3a) Do context.getBeanInfo().getProperty(myName) and return the type

for a parameter
4a) Ask the constructor/beanMetaData to guess which constructor
will be used from the BeanInfo.getConstructors() and then
determine the class from this.

The factory and create/.../destroy/install will be the same as the
constructor except at least for the factory/install they will have
to retrieve the bean info for a different type.

Again all this code is in the Configurator in terms of resolving/guessing
the specific info.
