[Po4a-devel]Nested blocks with Xml.pm

Hi all, I started looking at using Xml.pm for Xhtml last night. Is there an example somewhere of how one would go at processing nested blocks with Xml.pm? As it is, having defined the 'block' tags and 'inline' tags, it would produce only one msgid for, e.g.: <div> <h1>blah blah</h1> <p>This is a paragraph</p> </div> because <div> created a block and Xml.pm doesn't descend into blocks (as I understand it -- I may be confused).
