What's wrong in this schema?

[josandres]

Good morning:
I'm trying to use JAXB and i have written the following schema:

<xsd:complexType name="MetaInformation"> <xsd:sequence> <xsd:element name="description" type="xsd:string" default=""/> <xsd:element name="keyword" type="xsd:string" maxOccurs="unbounded" minOccurs="0" default="" /> </xsd:sequence> </xsd:complexType> <xsd:complexType name = "xmldisplaydefinition"> <xsd:attribute name="identifier" type="xsd:string"/> <xsd:attribute name="kindOfDisplay" type="xsd:string"/> <xsd:sequence> <xsd:element name="metaInformation" type="MetaInformation" maxOccurs="1" minOccurs="0"/> </xsd:sequence> </xsd:complexType>

when i validate my schema i receive the following error:

Invalid per cvc-complex-type.1.2.4: element {http://www.w3.org/2001/XMLSchema}:sequence not allowed here (5) in element {http://www.w3.org/2001/XMLSchema}:complexType, expecting
[{http://www.w3.org/2001/XMLSchema}:anyAt ... ibuteGroup]

Sorry for the bad formatting

<xsd:complexType name="MetaInformation"> <xsd:sequence> <xsd:element name="description" type="xsd:string" default=""/> <xsd:element name="keyword" type="xsd:string" maxOccurs="unbounded" minOccurs="0" default="" /> </xsd:sequence> </xsd:complexType> <xsd:complexType name = "xmldisplaydefinition"> <xsd:attribute name="identifier" type="xsd:string"/> <xsd:attribute name="kindOfDisplay" type="xsd:string"/> <xsd:sequence> <xsd:element name="metaInformation" type="MetaInformation" maxOccurs="1" minOccurs="0"/> </xsd:sequence> </xsd:complexType>

Hi

The error message occurs because the 'xsd:sequence' element must be declared before declaring any attributes in the complex type. The correct schema should look like this :

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

    <xsd:complexType name="MetaInformation">

        <xsd:sequence>

            <xsd:element name="description" type="xsd:string" default=""/>

            <xsd:element name="keyword" type="xsd:string" maxOccurs="unbounded" minOccurs="0"

                default=""/>

        </xsd:sequence>

    </xsd:complexType>

    <xsd:complexType name="xmldisplaydefinition">

        <xsd:sequence>

            <xsd:element name="metaInformation" type="MetaInformation" maxOccurs="1" minOccurs="0"/>

        </xsd:sequence>

        <xsd:attribute name="identifier" type="xsd:string"/>

        <xsd:attribute name="kindOfDisplay" type="xsd:string"/>

    </xsd:complexType>

</xsd:schema>

Best regards,
