Thank you for pointing out this problem with the documentation.

The correct behavior in accordance the 1.2 Errata A specs is the following:

The pcrComposite object is only used as input parameter. Thus no actual 
PCR values will be set in it or returned with it.
If you need to know the single PCR values, you have to extract them with 
  getPcrValue() of class TcPcrCompositeBase.

The current software implementation is in line with the specification, 
so I will update the documentation with the next release.

Regards, Ronald
