RE: Imports do not seem to have any effect in validators.

Thanks to everyone for your help, with your advices I've followed the way to solve the problem so now it validates against the schema I wanted.

Thanks again for your help.

Asunto: RE: Imports do not seem to have any effect in validators.

You seem to have misunderstood what xs:import does. Schema A only needs to
import schema B if it makes use of definitions in schema B. Your
EFDs_reduced schema doesn't reference any definitions in Headers_reduced, so
there's no point in importing it. Your two data documents are both in the
namespace of EFDs_reduced, so they are both validated against the
definitions in EFDs_reduced.

You say "the schema which defines the Header tag is imported in the main
one". The imported schema defines a complex type called Header in namespace
http://www.gal-gms-ete.esa.int. But no-one ever refers to that type, so it
might as well not be defined. There's certainly no magical association
between this complex type and the element definition with local name Header
and namespace http://www.gal-gms-ete.esa.int/EFD in the other schema
document. They would be unrelated even if the names matched.

Declaring a local element like this:

<xsd:element name="Header" minOccurs="1"/>

allows <Header> to have any content it likes. The only way to refine this
definition is to create a type that's derived by restriction from the
complex type in which this local element definition appears - however, in
this case you can't do that, because the complex type is anonymous.
