DOCBOOK-APPS: profiling "swallows" informaltable

hi list,

i am using the profile-chunk stylesheet for profiling. the profiling itself
works like a charm, saxon only outputs the desired sections.

BUT: i have an informaltable inside an example. the example is in the
html-output, but the informaltable is simply missing. the informaltable
isn't inside a "optional" part, i.e. should be seen for all roles.

i even tried the profiling for fo output - same effect.
without profiling everything is present in the output (all formats).

has anybody encountered a similar problem?

i am using docbook xsl 1.56.1, saxon 6.5.2 on a win2k machine.

thanks for your help,
