+ * for these defaulted "version" fields, but it's what the examples
+ * for this construction use.  So far it has not mattered, as code
+ * using these definitions have only decoded ROAs, never encoded
+ * them.  We'll see if that breaks with encoding.
+ *
+ * Putting this section under conditional compilation is a hack to
+ * keep Doxygen's parser from becoming hopelessly confused by the
+ * weird OpenSSL ASN.1 macros.  Someday perhaps I'll have time to
+ * track down the problem in Doxygen's parser, but this works for now.
