+ * Generate classes for XSD types in the specified targetNamespace. By default, types in the
+ * targetNamespace of the first schema in the specified xsd or wsdl file are generated. Specify
+ * 'all' and this parameter will act as a wildcard selecting all namespaces for code generation.
+ * -namespaceInfo
+ * Specifies the name of a file that should contain a list of namespaces and their associated package names.
+ * Optionally, a prefix may be assigned to each namespace as well. These values are separated by semicolons.
+ * So each line in the file would look something like this:
+ *
+ * some\namespace;custom.package.name;optionalPrefix
+ *
+ * NOTE: see the base class JavaGenerator for other options.
+ *
+ * Example:
+ *
+ * generate somedir/somefile.xsd
