The TDML Runner's embedded schemas currently default to constructing schemas with elementFormDefault='qualified'. This is probably a mistake, but many many tests would be broken if we changed this.

A feature should be added to tdml:defineSchema allowing the tdml file author to specify elementFormDefault='unqualified' or 'qualified' explicitly.

Then going forward we should specify (usually) elementFormDefault='unqualified' which is the normal behavior for an external DFDL schema that does not take a position on elementFormDefault. (The elementFormDefault defaults to 'unqualified')
