docbook qandaset

[Mathieu Malaterre <mathieu.malaterre@gmail.com>]

Hi,

  I'd like to prepare some exercise for some presentation I will be
doing. I am looking at qandaset as it seems the most appropriate for
doing question and answer style document. However I'd like to hide the
answer when presenting the question.

I tried a simple approach using hard-break
(http://www.sagehill.net/docbookxsl/PageBreaking.html). But this fails
with:

  Error reported by XML parser: The prefix "fo" for element "fo:block"
is not bound.

I cannot add a <?hard-pagebreak?> within <qandaentry/> element.

So my question is: is there another way of doing this ?
My initial approach was to use foil (from slides), but there is not
such properties as foil.autolabel for numbering of questions.

I am generating PDF output so I cannot use:
