Örnek XSD dosyası: Müşteriler ve siparişler (LINQ to XML)

Aşağıdaki XSD dosyası LINQ to XML belgelerindeki çeşitli örneklerde kullanılır. Bu dosya, Örnek XML dosyası için bir şema tanımı içerir: Müşteriler ve siparişler. Şema, XSD'nin ve özelliklerini kullanarak xs:key öğenin özniteliğinin Customer bir anahtar olduğunu CustomerID belirler ve her öğedeki öğesi ile CustomerID her OrderCustomer öğedeki öznitelik arasında CustomerID bir ilişki xs:keyref kurar.

yan tümcesini kullanarak Join bu ilişkiden yararlanan LINQ sorguları yazma örneği için bkz . İki koleksiyonu birleştirme.
