po4a checks if the external identifier (public or system) contains
"docbook xml". This should work for most valid official docbook Public
identifier. (I think "DocBk XML" can also occur)

So
	<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN">
should be accepted by po4a.

I don't think I can check automatically system identifiers since they
could be basically anything.

I would recommend that you use the -o doctype=docbook option to work
around this limitation.
