Hello everybody. I was asked to supply FIXML schema files to one of our customers to reflect the FIX dialect of our application. I read the file-layout documentation on http://fixwiki.org/fixwiki/FPL:FIXML_Syntax#FIXML_Schema_File_Structure and try to conform to this standard.
I noticed the separation between base and impl files, where impl includes base. I understand that in fixml-fields-impl, I can customize enumeration datatypes, but how would I customize components and messages, i.e. remove/alter/add elements and attributes?
