Already in the SDF->CDK node? I thought about adding them in the XLogP 
node if necessary. Are there any situations, where explicit hydrogens 
can hurt? If not, then we can really do this upon conversion to CDK.

What exactly do you mean with that? Should molecules with S or P 
excluded from the calculation (what is TPSA BTW :-*))?

Hm, I have to check, if the CDK descriptors offer such a possibility.

Jep, that's a good point. Noted for 2.0 :-)
