Jørn,

I wouldn't mind doing this.  Please submit a bugreport against OGR
with an example of a GML 3.1 file that you think would work if the
gml:pos handling was added.  I will attempt to add it in the fairly
near future.

This is possible, but I have avoided it in the past due to the
complexity.  I am assuming that nested elements would be
treated as having unrolled column names?

so
<date>
  <year>2005</year>
  <month>December</month>
  <day>25</day>
</date>

would appear in the result as attributes:
date_year: 2005
date_month: December
date_day: 25

Does that seem reasonable?  Please file a separate bug
report with this suggestion but I don't have any plans to
do it in the near term.

Best regards,
