How to write XSD for an XML File

[asma1400]

This is my XML File:

<?xml version="1.0" encoding="UTF-8" ?> <rooms xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="room.xsd">
 <room> 
<capacity>2 Adults</capacity>
 <room_name>King Double</room_name> <cost_st>$1700</cost_st> 
<cost_lt>$3400</cost_lt> 
<loc>Ground Floor</loc>
 <photo>fraise.jpg</photo> </room> </rooms>

This is my attempt at XSD, it's not working

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">

 <xs:complexType name="Image">
                                 <xs:simpleContent>
                                            <xs:extension base="xs:anyURI">
                                                 <xs:attribute name="src" type="xs:string"/>
                                                 </xs:extension>
                                  </xs:simpleContent>
                         </xs:complexType>
                         
        <xs:element name="rooms">
        <xs:complexType>
<xs:sequence>

<xs:element name="room" minOccurs="1" maxOccurs="unbounded">
 <xs:element name="capacity" type="xs:string"/>
                           <xs:element name="room_name" type="xs:string"/>
                           <xs:element name="cost_st" type="xs:string"/>
                           <xs:element name="cost_lt" type="Image"/>
         <xs:element name="loc" type="xs:string"/>
                           <xs:element name="photo" type="xs:Image"/>
        
      </xs:element>
      </xs:sequence>
      </xs:complexType>
      </xs:element>
      </xs:schema>
