I was a member of the ISDA/FpML Validation Working Group and also the FIXML Schema WG. For FpML we established a set of business validation rules and attempted to implement them in Schematron and CLIX. For our purposes, Schematron was not able to handle the complexity of some of the business rules for OTC Derivative Contracts, however CLIX was. Areas where we ran into trouble for FpML usually involved verifying intermediate payment date schedules given a start and end date.
This may not be an issue for FIXML as listed assets are well specified either by an exchange or the issuer. Determining that the proper elements and attributes are included for various messages should be straight forward. Actually verifying the data values for those elements, or attributes, may not be. Schematron seems to fall short if computation, or extrapolation, based on data is required.
