This is a nice addition, but it doesn't make the calls to node-expat itself async - the process still has to wait on the parser.parse() call to complete. Maybe implementing something similar to [this](https://github.com/wahvee/node-expat/commit/380f584cbc1e389e234ad1350994ad356479a540) (in JS instead of C) could make the call async and thus the callback really useful.
