It will be a mixed bag of SMILES errors, duplicated structures,
incorrect activity entries, .... Examples can be found e.g. at
http://toxcreate.org/models under "Warnings:  show".  Simple string
annotation for concatenated error/warning messages could be sufficient.

Yes, this is a different story. During dataset parsing I try 
to parse as much information as possible and to present errors/warnings
later.
