Bind Choice Example
The Bind Choice example shows how to bind a
choice
model group to a Java
interface. Like the External Customize and Fix Collides examples, the Bind
Choice example uses an external binding declarations file,
binding.xjb
, to
define the JAXB binding customization.
The schema declarations in
<INSTALL>/examples/jaxb/bind-choice
/example.xsd
that will be globally changed are highlighted in bold below.
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
