/**
+ * This function is initially called for all egos and then again

+ * with 'NULL' for 'ego'. That does NOT mean that the callback won't
+ * be invoked in the future or that there was an error.
+ *
+ * When used with 'GNUNET_IDENTITY_create' or 'GNUNET_IDENTITY_get',
+ * this function is only called ONCE, and 'NULL' being passed in
+ * 'ego' does indicate an error (i.e. name is taken or no default
+ * value is known). If 'ego' is non-NULL and if '*ctx'
+ * is set in those callbacks, the value WILL be passed to a subsequent
+ * call to the identity callback of 'GNUNET_IDENTITY_connect' (if
+ * that one was not NULL).
+ *
+ * When an identity is renamed, this function is called with the
+ * (known) ego but the NEW identifier.
*
+ * When an identity is deleted, this function is called with the
+ * (known) ego and "NULL" for the 'identifier'. In this case,
+ * the 'ego' is henceforth invalid (and the 'ctx' should also be
+ * cleaned up).
