FIXatdl1.1 Errata 20101221 Errata for FIXatdlSM Specification version 1.1 December 21, 2010 Purpose: This document contains a list of minor adjustments to the FIXatdl 1.1 Specification document due to typographical errors or ambiguities. The nature and scope of these adjustments is restricted such that no new functionality is introduced, and the goal of these Errata is that no breaking changes are introduced. NOTE: In order to meet this goal, no functional changes have been made to the FIXatdl 1.1 XSD schema files. This means that where the schema and the Word specification disagree, then the Word specification should be taken as the authoritative definition of the protocol. The known variations between the schema and the Word document are listed at the end of this document. Outstanding Issues: Issues with the FIXatdl 1.1 Specification which have not been addressed by the combination of the FIXatdl 1.1 Specification document or this Errata document should be brought forward via the FIX web site (http://www.fixprotocol.org) discussion pages. It is the responsibility of the Algorithmic Trading Working Group to see that outstanding issues are addressed. The Algorithmic Trading Working Group is co-chaired by Rick Labs, CL&B Capital Management ([email protected]) and Greg Malatestinic, Jordan & Jordan ([email protected]). Changes to the FIXatdl Specification Document ID/JIRA # ATDL-146 Item/Area Affected Label_t Description It was not previously clear whether a label’s text should be initialized from the initValue attribute or the label attribute. This has been clarified and a precedence rule given. Clarification on how CheckBoxList_t items should be separated. The StrategyLayout element if supplied must contain exactly one StrategyPanel. Clarified to be “true” / “false” or “Y / “N” as appropriate. This attribute was missing from the Word document. This attribute was missing from the Word document.

This is now a mandatory attribute of CheckBoxList_t and RadioButtonList_t controls (as there is no way programmatically to determine a sensible default value). An example provided at the end of the section made use of a deprecated attribute. Another example using valid attributes was added.
