xml_to_binary turns an SI to a data directory with encoded binary SI and image data, along with a manifest encode_manifest encodes the manifest into a directory bitstream. These libraries to do this are not currently publicly available.

./xml_to_binary -e e1.c1c8 SI.xml ./encode_manifest -p -o out data

you can decode the data using the python-msc decode script (again, not currently publicly available :(

python ~/git/python-msc/bin/decode.py -p -d -o -m mot.epg out
