example and Section 2.9.2, "Element Map" in the C++/Tree Mapping
User Manual.
+ * Prior to this version when the --generate-polymorphic option is
+ specified the compiler treats all types as potentially polymorphic.
+ Now by default only type hierarchies used in substitution groups and
+ those explicitly declared polymorphic with the new --polymorphic-type
+ option are treated as polymorphic. This results in smaller and faster
+ generated code. If you would like to continue using the old behavior,
+ you will need to specify --polymorphic-type-all. For more information
+ on this change see Section 2.11, "Mapping for xsi:type and Substitution
+ Groups" in the C++/Tree Mapping User Manual.
* New option, --export-xml-schema, causes the compiler to export/import
types in the XML Schema namespace using the export symbol provided
with the --export-symbol option.
