that in case both object_type tags exist and an object type is present
in md
See #5
Background for the disabling of exports of the regular object type in
case both exist: The German Digital Library (DDB) is unable to handle
duplicate names in work types unless both contain different links to
norm data repositories. This fix allows the DDB to more easily import
while supposedly not losing meaningful data.
Currently, the export generates (erroneously, I guess) an `xmlns:schemaLocation` namespace and consequently doesn't link the gml schema properly. I've changed the attributes in `lido:lidoWrap` to fix this issue.
