Probably so in theory you can have multiple parse operations running all using
the same callback functions, but routing data into different places using the
parser object to differentiate between instances?

Although it's probably neater to just use an object method callback to do this
instead of a global function callback, and I'd guess having multiple parse
operations on the go at the same time in a PHP script is rare enough anyway.
