Have you also looked in the FIX Specification, Volume 1 under FIXML Design Rules starting on page 29? For example, it says "The default version fixml-components-impl file simply redefines the components-base file. This is the file where modifications (restrictions or extensions) would be made to component blocks used in the FIX protocol."
