Pointing all the namespace prefixes at the same fictuous namespace
definitions is obviously wrong.
What exactly was their suggestion? The above is unquestionably broken.
Looking at the result of this request:

You can see above proper prefix/namespace associations. What is it that's
tripping OGR in your
case? If it's the schema location and OGR can only work if the schema
location for WFS is pointing
at http://schemas.opengis.net/wfs/1.1.0/wfs.xsd instead would fix it then
yeah, selecting "use canonical
schema locations" should fix your issues.
One thing though, if I try to translate the above in, say, kml with ogr2ogr
it works without issues:
ogr2ogr -f kml /tmp/test.kml /tmp/gml.xml
<?xml version="1.0" encoding="utf-8" ?>
<kml xmlns="http://www.opengis.net/kml/2.2";>
<Document><Folder><name>missions</name>
<Schema name="missions" id="missions">
<SimpleField name="Name" type="string"></SimpleField>
<SimpleField name="Description" type="string"></SimpleField>
<SimpleField name="gml_id" type="string"></SimpleField>
<SimpleField name="mission_id" type="int"></SimpleField>
<SimpleField name="cruise_id" type="int"></SimpleField>
<SimpleField name="start_date" type="string"></SimpleField>

Soo... I'm not sure what is wrong on your end?
