I've just released the 3.0-alpha3 version of my XINS fork, which includes the also just released Logdoc 0.2. See:
XINS 3.0-alpha3 introduces lots of small changes, mostly cleanup and minor corrections. A functional change is the introduction of client-side transaction logging via the log messages 2300 and 2301. The former includes the input/output parameters, while the latter does not.
Note that my XINS 3.0 fork is based off XINS 2.2-alpha2. Porting the changes from the 2.x branch to my 3.0-fork is one of my next challenges. Help in this area would be much appreciated! If you are keen and precise and know a bit about Java coding, let me know via ernst [at] ernstdehaan com.
