EP076 – FIX.5.0SP1 FIXML Errata

This is a collection of FIX 5.0 SP1 FIXML schema defects rather than a business-workflow proposal. It records issues involving Security Definition leg-group structure and abbreviation, inconsistent derivative-security-status abbreviations, inconsistent price-limit abbreviations, missing or incorrectly required fields in Derivative Security List, and a question concerning FillsGrp schema content.

The problem being solved is schema correctness and interoperability. Incorrect group cardinality, duplicate element abbreviations, inconsistent attribute names and missing fields can cause generated FIXML schemas or implementations to represent valid FIX structures incorrectly. EP76 records the required corrections for the SP1 errata and subsequent service-pack work.
