Connecting an xsd schema to an xml file

Question

Connecting an xsd schema to an xml file

Xml:

 <?xml version="1.0" encoding="UTF-8"?>
 <students xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="students.xsd">
 <student id = "1">
   <name>Елизавета</name>
   <surname>Карпова</surname>
   <fathername>Константиновна</fathername>
   <university>СпБГУ</university>
 </student>
</students>

Xsd schema:

 <?xml version="1.0" encoding="UTF-8"?>
 <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
 <xs:element name = "students">
 <xs:complexType>
  <xs:sequence>
   <xs:element name = "student">
    <xs:complexType>
     <xs:sequence>
      <xs:element name = "name" type = "xs:string"/>
      <xs:element name = "surname" type = "xs:string"/>
      <xs:element name = "fathername" type = "xs:string"/>
      <xs:element name = "university" type = "xs:string"/>
    </xs:sequence>
 </xs:complexType>
</xs:element>

Both files are in the same folder.

Error:

Sannot find declaration of element students

The students element is described, what's wrong?

The error is that xml does not match the xsd schema:

<student id = "1">

But in the xsd schema, student does not have the id attribute. Schema with added attribute id:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name = "students" >
<xs:complexType>
  <xs:sequence>
    <xs:element name = "student" >
    <xs:complexType>
      <xs:sequence>
        <xs:element name = "name" type = "xs:string"/>
        <xs:element name = "surname" type = "xs:string"/>
        <xs:element name = "fathername" type = "xs:string"/>
        <xs:element name = "university" type = "xs:string"/>
      </xs:sequence>
      <xs:attribute name="id" type="xs:int"/>
    </xs:complexType>
    </xs:element>
  </xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
