We have an HDP/MCAP implementation that uses this functions. We are going to 
release it this week.  Sancane and I are solving some problems with this code. 
We will announce here when this code is available.

About the patch to  sdptool: I didn't do anything but I can do it if you think 
that is a good task.

I made some changes correcting all the problems that you suggested an other 
that I found.
