RFC 3504                     IOTP v1 Errata                   March 2003
1. Introduction
The Internet Open Trading Protocol (IOTP), Version 1.0, is specified in [RFC 2801, 2802, 2803]. It provides a payment system independent framework for Internet commerce oriented to consumer to business transactions. It provides mechanism for different portions of the business function, such as fulfillment or payment handling, to be distributed or outsourced. It does not require a prior relationship between the consumer and business.

Several errors have been noted in the IOTP v1.0 specification, particularly RFC 2801, which was the largest RFC ever issued. These are listed, with their fix, in this document.
2. DTD Errata

2.1 PackagedContent Element
Attribute types are swapped.

OLD/INCORRECT: !ELEMENT PackagedContent (#PCDATA) > <!ATTLIST PackagedContent
               Name             CDATA     #IMPLIED
               Content          NMTOKEN   "PCDATA"
               Transform   (NONE|BASE64)  "NONE" >
NEW/CORRECT:
<!ELEMENT PackagedContent (#PCDATA) > <!ATTLIST PackagedContent Name NMTOKEN #IMPLIED Content CDATA "PCDATA" Transform (NONE|BASE64) "NONE" >

RFC 3504                     IOTP v1 Errata                   March 2003
2.2 The Element called Attribute
Incorrect element content specification syntax.

OLD/INCORRECT: <!ELEMENT Attribute ( ANY ) > <!ATTLIST Attribute type NMTOKEN #REQUIRED critical ( true | false ) #REQUIRED
>

NEW/CORRECT
<!ELEMENT Attribute ANY > <!ATTLIST Attribute type NMTOKEN #REQUIRED critical ( true | false ) #REQUIRED
>
3. Other Errata

3.1 Re: Combining Authentication Transactions with other Transactions
Section 9.1.13. page 234, restarted->continued:

OLD/INCORRECT: if the Authentication transaction is successful, then the original IOTP Transaction is restarted

NEW/CORRECT:
if the Authentication transaction is successful, then the original IOTP Transaction is continued
3.2 Type attribute of Element called Attribute
Section 7.19.1, Page 150, insufficient list of signature types:

OLD/INCORRECT:
There must be one and only one Attribute Element that contains a Type attribute with a value of IOTP Signature Type and with content set to either: OfferResponse, PaymentResponse, DeliveryResponse, AuthenticationRequest, AuthenticationResponse, PingReq or PingResponse; depending on the type of the signature.
Eastlake                     Informational                      [Page 3]

RFC 3504                     IOTP v1 Errata                   March 2003
NEW/CORRECT:
There must be one and only one Attribute Element that contains a Type attribute with a value of IOTP Signature Type and with content set to either: OfferResponse, PaymentResponse, DeliveryResponse, AuthenticationRequest, AuthenticationResponse, PingReq, PingResponse, AuthenticationStatus, InquiryRequest, or InquiryResponse; depending on the type of the signature.

AND a similar change extending the list of values in Section 12.1, Page 262.

And at Section 6.1.2, Page 82, add the following:

AuthenticationStatus any role

InquiryRequest any role

InquiryResponse any role
4. Security Considerations
The errata listed herein are not particularly security related. Never the less, incorrect implementations due to uncorrected errors in the specification may compromise security.
