difference between RFC 1423 and X.509

Has anobody noticed that there is a difference between "rsa" object 
identifier defined in RFC 1423, and the same identifier defined in X.509 
ANNEX H.

In PEM RFC 1423, in chapter 4.1.1 RSA Keys, two ASN.1 object identifiers 
are defined for identification of RSA keys. They are:




1) rsa  OBJECT IDENTIFIER ::= {
     joint-iso-ccitt(2) ds(5) algorithm(8)
     encryptionAlgorithm(1) 1
   }


and

2) rsaEncryption OBJECT IDENTIFIER ::= {
     iso(1) member-body(2) US(840) rsadsi(113549) pkcs(1)
     pkcs-1(1) 1
   }




But when you look into X.509 ANNEX H, object identifier for 'rsa'
is defined in following way

rsa OBJECT IDENTIFIER ::=  {
     joint-iso-ccitt(2) ds(5) 
     modules(1)  /********/
     algorithm(8)
     encryptionAlgorithm(1) 1
}



Has this been noticed before? If so, what is the conclusion? I suppose this 
is an error in RFC 1423.
