True. This implementation of ISO 14443-3 Type A cards seems to differ from the standard for both Classic and Ultralight code... at least in two important aspects: a) accepting REQA/WUPA in any state and b) not differentiating between IDLE and HALT states.
@david-oswald Could you let us know the reasons behind this divergence from the standard? Should we submit patches to rectify this?

You could submit patches. A good approach would be to change the ISO14443AWakeUp function or splitting it up in two functions that check for WUPA and REQA seperately. Also, the states inside the card emulation applications have to be changed.
So: If you find time to change this to the standard right now, you could submit a patch. But we also have this on our agenda, although this may need more time than if you do it.
