Yes, that's what I'm talking about! I think the GNU Taler wallet would
be a good place to integrate the implementation of such a standard
(which we might have to design first!), as it already manages "receipts"
of purchases. If I'm already using GNU Taler to buy stuff with
electronic cash, I don't see why I would want a separate app with
separate synchronization / backup to store my electronic receipts for
purchases with on-electronic cash.
If we implement such a feature *really well* in the GNU Taler wallet, of
course based on an open standard, it might be a way to get more users
and merchants to know about the rest of GNU Taler too.

I'm a happy user of PassAndroid myself, but it serves a different
purpose, as far as I know. It doesn't have any backup & synchronization
features, something that we have to get right for Taler anyway.
Same with "graphs and analytics", it's something we want for the GNU
Taler wallet anyway (we already had a GSoC student working on it,
unfortunately they dropped out). This can then easily be re-used for
the E-Bon / electronic purchase receipts.
Of course developing an open standard and then implementing it in our
wallet doesn't stop other apps like PassDroid from offering it too.
