We are doing exactly this with great success! There are some additional caveats if you are re-using a grammar (passing true for the second parameter to parse()). Though we use schema exclusively.
1. Grammar will be defined by the first parse. 1. Any errors encountered when parsing the original schema (the first since its the only time it will be parse) will result in a truncated grammar definition that may result in validating invalid documents.
