8.12.1 Java ID in XML Name

The following shows the default mapping for different identifiers:

• class name: the class name is mapped to the XML name by capitalization using java.beans.Introspector.decapitalize (class name).
• enumtype name: enumtype name maps to XML name using capitalization java.beans.Introspector.decapitalize (enumtype name).
• The property name (e.g. address) is derived from the JavaBean access method (e.g. getAddress) from JavaBean de capitalization of JavaBean Property name java.beans.Introspector.decapitalize (JavaBeanAcc essMethod)
