Parser error XML: the attribute 'type' and the <complexType> child are mutually exclusive

Question

hello I have been looking on this isse for about an hour and I couldnt find what that even should mean.

Here is my XML shema code:

<xsd:element name="game">
    <xsd:complexType>
        <xsd:sequence>
        <xsd:element name="info" minOccurs="0" maxOccurs="1" type="infoType">   
        </xsd:element>
        <xsd:element name="moves" type="movesType" minOccurs="1">

        </xsd:element>
        </xsd:sequence>
    </xsd:complexType>
</xsd:element>
<xsd:complexType name="infoType">
    <xsd:sequence>
        <xsd:element name="name" minOccurs="0" maxOccurs="1" type="xsd:string"></xsd:element>
        <xsd:element name="description" minOccurs="0" maxOccurs="1" type="descriptionType">
        </xsd:element>
        <xsd:element name="started" type="xsd:dateTime"></xsd:element>
        <xsd:element name="players" minOccurs="0" maxOccurs="1">    
            <xsd:complexType>
                <xsd:sequence>
                    <xsd:element name="screenname" minOccurs="0" maxOccurs="4" type="xsd:string">
                        <xsd:complexType>
                            <xsd:attribute name="player"  use="required">   </xsd:attribute>
                        </xsd:complexType>

<xsd:complexType name="movesType">
    <xsd:choice maxOccurs="unbounded">
        <xsd:element name="roll" >

                    </xsd:restriction>
                </xsd:simpleContent>

                        </xsd:restriction>

                <xsd:attribute name="field" type="xsd:integer" use="required">

                            <xsd:minInclusive value="1"></xsd:minInclusive>

                    </xsd:simpleType>
                </xsd:attribute>
            </xsd:complexType>
        </xsd:element>
    </xsd:choice>
</xsd:complexType>
<xsd:simpleType name="playerType" >
    <xsd:restriction base="xsd:integer">
        <xsd:minInclusive value="1"></xsd:minInclusive>
        <xsd:maxInclusive value="4"></xsd:maxInclusive>
    </xsd:restriction>
</xsd:simpleType>
<xsd:complexType  name="descriptionType" mixed="true">
                <xsd:choice minOccurs="0" maxOccurs="unbounded">
                    <xsd:element name="i" type="descriptionType" ></xsd:element>
                    <xsd:element name="b" type="descriptionType"></xsd:element>
                </xsd:choice>
            </xsd:complexType>

and here is the parser error that I get for it.

game.xsd:25: 
  element complexType: 
  Schemas parser error : 
  Element '{http://www.w3.org/2001/XMLSchema}element': 
  The attribute 'type' and the child are mutually exclusive. 
game.xsd:51: 
  element attribute: 
  Schemas parser error : 
  Element '{http://www.w3.org/2001/XMLSchema}complexType': 
  The content is not valid. Expected is (annotation?, (simpleContent | complexContent | ((group | all | choice | sequence)?, ((attribute | attributeGroup)*, anyAttribute?)))). 
game.xsd:58: 
  element simpleType: 
  Schemas parser error : 
  Element '{http://www.w3.org/2001/XMLSchema}attribute': 
  The attribute 'type' and the child are mutually exclusive. 
game.xsd:66: 
  element simpleType: 
  Schemas parser error : 
  Element '{http://www.w3.org/2001/XMLSchema}attribute': 
  The attribute 'type' and the child are mutually exclusive. WXS schema game.xsd failed to compile

This is for a university project, and I have to turned in in 6 hours. I hope I can find a solution in this time.

Thanks

The attribute 'type' and the child are mutually exclusive.

In the element definition for screenname (game.xsd:25) both defined the element type to be xsd:string in an attribute AND defined it as a complexType using a child element. You are probably looking for a type with a specific attribute and a string content?

<xsd:element name="screenname" minOccurs="0" maxOccurs="4">
  <xsd:complexType>
    <xsd:simpleContent>
      <xsd:extension base="xsd:string">
        <xsd:attribute name="player" use="required" type="xsd:string" />
      </xsd:extension>
    </xsd:simpleContent>
  </xsd:complexType>
</xsd:element>
