You will have to override it. What I would expect to see is a separate
Configuration instance for "complex GML", which re-uses much of the non
complex stuff. In the complex configuration a different binding will be
attached to GML.AbstractFeatureType

There should be only one.

The binding will have to be dynamic in nature, like
AbstractFeatureTypeBinding is today. It does not not know what actual
feature type it is parsing, it looks it up dynamically basked on the
element actually being parsed. Although it uses a fall back to get
around the fact that most people do not ever specify there application
schema properly.
But if you look at the class and follow it down you will eventually hit
the method:
GML2ParsingUtils.featureType(XSDElementDeclaration element,
BindingWalkerFactory bwFactory);
This is the method that takes an xml element declaration and from its
type builds a feature type from it. I imagine you will have to write a
complex version of this method which handles complex content.
