xsd

[timothy-tim@lycos.com]

I am fairly new to XSD so I assume this is probably a FAQ.

I have a Complex Type say "Foo" which is present as child element of
many xs:element.

In just one of these elements Bar, I want Foo to have additional
attributes/Facets

for example in the schema below
<xs:complexTy pe name="Bar">
<xs:sequence>
<xs:element name="Foo" type="Foo" maxOccurs="unbo unded"
minOccurs="0">
</xs:element>
</xs:sequence>
</xs:complexType>

I want Foo to have an additional attirubtute called IsTrue="xs:Bool ean"


How do I achive this? Do I have to declare a new type for this?

Re: xsd

Hi,

Yes, you need to declare a new type that will extend Foo and will add
the attribute that you want. You can do that either with a local type
declaration like

<xs:element name="Foo" maxOccurs="unbo unded" minOccurs="0">
<xs:complexType >
<xs:extension base="Foo">
<xs:attribute name="isTrue" type="xs:boolea n"/>
</xs:extension>
</xs:complexType>
</xs:element>

or by defining a new named type and refer to that instead of Foo.

Best Regards,
George
