Overview
A FIX dictionary is an XML-file which that describes FIX messages, fields and groups. A FIX dictionary can be:
- a self-sufficient dictionary which that describes the FIX protocol;
| Info |

FIX Antenna JAVA dictionaries have the same format as FIX Antenna C++/.NET dictionaries |
- an additional dictionary which that describes changes that are to be applied to another existing dictionary.
...
When FIX Antenna is started, all dictionaries from DictionariesFilesList are loaded. If dictionaries are standard, predefined standard parsers (like FIX40; FIX41; FIX42; FIX43; FIX44; FIXT11) are created basing on them. If any dictionary from DictionariesFilesList is custom, the parser is not automatically created and therefore such parsers should be listed manually in AdditionalParsersList parameter.
