  • EPAM products have their own format, that closely mimics the structure of official FIX specification, leveraging "block" elements and references, defining type system, and some more. Additionally, besides runtime metadata, it also contains human-readable textual details about message & tag meaning.
  • The QuickFIX dictionary is natively supported by FIX Antenna C++ since  FIX Antenna C++ 2.28.0 and no longer requires manual conversion to FIX Antenna format.

There is no way to remove elements from the base FIX dictionary
