Extending and adding attributes

[ahundiak]

I am trying to extend a complex type and add some additional attributes.

<xs:complexType name="EntityType" abstract="true">
<xs:attribute name="id" type="xs:ID" use="optional"/>
<xs:attribute name="href" type="xs:anyURI" use="optional"/>
</xs:complexType>

<xs:complexType name="EdoType">

<xs:complexContent >
<xs:extension base="EntityType"/>
</xs:complexContent>

<xs:attribute name="X-href" type="xs:anyURI"/>
</xs:complexType>

Oxygen complains about the attribute being invalid or misplaced.

Hi,

That is a basic error. If you use complexContent as a child if complexType you cannot have other elements following complexContent. You should place the attribute inside the xs:extension element as below:

Code: Select all

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

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

    <xs:complexType name="EntityType" abstract="true">

        <xs:attribute name="id" type="xs:ID" use="optional"/>

        <xs:attribute name="href" type="xs:anyURI" use="optional"/>

    </xs:complexType>

    

    <xs:complexType name="EdoType">        

        <xs:complexContent >

            <xs:extension base="EntityType">

                <xs:attribute name="X-href" type="xs:anyURI"/>

            </xs:extension>            

        </xs:complexContent>

    </xs:complexType>

    

</xs:schema>

Best Regards,
