History
The proposal was accepted at the November 2011 meeting.This feature is implemented in the CCID reader revision 6258 and will be available in the next CCID driver release.

PCSCv2_PART10_PROPERTY_dwMaxAPDUDataSize in OpenSC and display a clear message to the user.Conclusion
PCSCv2_PART10_PROPERTY_dwMaxAPDUDataSize is now available for you. Use it if/when you need this feature.
