This is slightly off topic, but related to how Saxon-SA and Saxon-B handle large files. From my testing, Saxon-B is limited to working with XML files in the range of 100 MB. Anything much over that size Saxon-B will choke with a Java out of memory error. Since I'm typically working with XML files in the range of 500 MB to 900 MB size I have found Saxon-B to not be up to the task. Does anyone know whether Saxon-SA will process large XML datasets in the 500 MB to 900 MB size range.
