-%D Currently there is a limitation in mixed inline usage. This has to do with the fact
-%D that we have a stacked model but cannot determine where to revert to (as we can
-%D have AABBCCAA ranges). Maybe I'll solve that one day. It only affects nested inline
-%D layers and these make not much sense anyway. We'd have to store the complete nesting
-%D stack in the attribute in order to be able to cross pages and that demands a new
-%D mechanism.
