I saw this on the openSUSE project mailing list, … which is the GSOC 2011 sax3 work report:
SaX3 – GSoC 2011 – Work Report
It will be interesting to see how far the sax3 development gets …
I know a number of users are REALLY keen on seeing this move forward.
This was in part as a response to the populate openFATE feature request: https://features.opensuse.org/308357
