Kalev,

OK, this is fixed in CVS now.  The default action now is to write a .xsd file
with the same basename as the GML file.  The XSISCHEMAURL creation option may
be used to turn off schema writing, and force a reference to an existing
schema file.  The XSISCHEMA=INTERNAL option may be used to force schema
info to be written internally in the .gml file in the broken way you saw.
XSISCHEMA=OFF can be used to disable all reference schema files. The default
is now XSISCHEMA=EXTERNAL.

You can pick up the next nightly snapshot, or pull directly from CVS.

Best regards,
