Does anybody remember the reason why we strictly disallow nesting of bibliographies (the only style we do this btw)?
static bool changeDepthAllowed(Text::DEPTH_CHANGE type, Paragraph const & par, int max_depth) { if (par.layout().labeltype == LABEL_BIBLIO) return false; ... } In beamer, bibliographies will need to be nested (inside frame), and I also can imagine diverse other cases where nesting would be perfectly legitimate. I tend to remove this restriction altogether, but if someone comes up with a convincing reason why we should keep it for some reasons/classes, I will go for another solution (such as a "nestable" layout tag).
