any idea why a <qandaset> would be forced to the next page

as part of a sample markup document, i have a *very* simple
<qandaset>, after an introductory sentence, but when i generate
the PDF (xsltproc -> fop), the entire qandaset is being forced
to the next page.

  certainly, nothing i read in the semantics for qandaset suggests
this should happen.

  any advice?
