[Boost-docs] [boostbook] Docbook processing instructions get stripped out?

For some reason I'm seeing docbook processing instructions getting stripped 
out of the XML during the Boostbook->DocBook stage.

For example if I insert:

'''<?dbtimestamp format="Y-m-d H:M:S"?>'''

Into my quickbook source, then the processing instruction is present in the 
Boostbook source, but not in the Docbook source (and hence missing from 
final output).

Anyone any ideas?

Thanks, John.
