What I haven't been able to figure out is how to wrap sections in <section> tags.  That is, in the built in docbook writer, if you have a header, I think it creates a section with a title around the appropriate content.  Is there any way to do this with a custom lua writer?  

Perhaps a better approach would be to contribute a new built in writer by modifying the docbook writer.  I think there would be a good number of people who would find this writer useful.  Would such a contribution be considered?

Thanks,

Oscar.
