xs:ID (I think that's what you want for inp), xs:IDREF and xs:IDREFS
function the same as they do in DTDs -- see any introductory XML book
for details.

Something like

<xs:element name="GInP">
 <xs:complexType>
  <xs:sequence>
   . . .
  </xs:sequence>
  <xs:attribute name="inp" type="xs:ID" use="required"/>
 </xs:complexType>
</xs:element>

<xs:element name="Correspondance">
 <xs:complexType>
  <xs:sequence>
   . . .
  </xs:sequence>
  <xs:attribute name="corresplist" type="xs:IDREFS"/>
 </xs:complexType>
</xs:element>

or maybe I have the attributes on the wrong elements, I wasn't sure
from your description.

See the Primer [1] for an overall introduction to elements and types,
and also the more powerful schema-native key and keyref.
