EP271 - No visible change in StandardHeader with the previous version

1

Hi Team,

We have been in the process of upgrading our FIXML to the latest extension pack.

One of the changes highlighted in EP271 is the abbr name of StandardHeader changed from BadeHeader to Hdr. But when you compare the schema from EP269, it was still Hdr and not BaseHdr. Please let me know what has changed between the previous version of FIXML in this case?

Regards
Rahul

@rahulmohanraj, you are right. The change only affected the repository formats Basic, Unified, and Orchestra. The FIXML schema file for components already used “hdr”. The issue should have been in section 2.2.

<xs:complexType name="Abstract_message_t">
      <xs:sequence>
         <xs:element name="Hdr" type="MessageHeader_t" minOccurs="0"/>
      </xs:sequence>
   </xs:complexType>

The definition of the StandardHeader in the repository files has changed with EP271 and now looks as follows in Orchestra:

      <fixr:component name="StandardHeader"
                      id="1024"
                      category="Session"
                      added="FIX.4.0"
                      updated="FIX.Latest"
                      updatedEP="271"
                      abbrName="Hdr">

Previously, it was abbrName="BaseHeader".
