Since the peek only virtual stream has already been rejected for another
issue, there's no way to wire our xmlreader to a non reading stream.
If we need to read to probe, that's wrong. Reading when probing breaks
other modules.
Unless there's a way to parse incomplete documents (pf_probe?), we can't
use libxml for probing.
