Problem exporting content with XMERL

[Bertil Karlsson]

Hi,

First, you have to pass the structure as a list:
xmerl:export_simple([dvbh_xml:simple()], xmerl_xml, [{title, "Doc 
Title"}]).

Second, when I ran your example with modified input I hit another error, 
which is a bug in xmerl.
Maybe I'll manage to deliver this bug-fix with R11.
