Property customization.
This customization turns an arbitrary schema component
into a Java property (some restrictions apply.)

All the getter methods (such as getBaseType or
getBindStyle) honors the delegation chain of
property customization specified in the spec. Namely,
if two property customizations are attached to an attribute
use and an attribute decl, then anything unspecified in the
attribute use defaults to attribute decl.

Property customizations are acknowledged
(1) when they are actually used, and
(2) when they are given at the component, which is mapped to a class.
    (so-called "point of declaration" customization)

Finds a property customization that describes how the given
component should be mapped to a property (if it's mapped to
a property at all.)

Consider an attribute use that does NOT carry a property
customization. This schema component is nonetheless considered
to carry a (sort of) implicit property customization, whose values
are defaulted.

This method can be think of the method that returns this implied
property customization.

Note that this doesn't mean the given component needs to be
mapped to a property. But if it does map to a property, it needs
to follow this customization.
I think this semantics is next to non-sense but I couldn't think
of any other way to follow the spec.
