<complexType name="hotel2">

          <attribute name="address1" type="string" fixed="A2"/>

     </restriction>

</complexType>

...
alowing XML like:
 

<Feature1 xmlns:xsi="...">

     <property1 xsi:type="hotel1" name="H1" address1="A1"/>

     <property1 xsi:type="hotel2" name="H2" address1="A2"/>

</Feature1>

Thank you much for your response. But I don't think I understood quite well, if you could give me an example, it would be great.
 
Thanks,
Shashi
 
For your reference I am attaching the XSD
 
<element name="Feature1" type="x1:Feature1"/> 
     

     <complexType name="Feature1">

          <sequence>

               <element name="property1" type="x1:hotel1" />

          </sequence>

     </complexType>

     

     <complexType name="hotel1">

          <attribute name="name" type="string" fixed="H1"/>

          <attribute name="address1" type="string" fixed="A1"/>

     </complexType>

     

     <complexType name="hotel2">

          <attribute name="name" type="string" fixed="H2"/>

          <attribute name="address1" type="string" fixed="A2"/>

     </complexType>

 

which would give me an XML like below

 

<Feature1>

     <property1 name="H1" address1="A1"/>

</Feature1>

 

but if I want an XML like below:

 

<Feature1>

     <property1 name="H1" address1="A1"/>

     <property1 name="H2" address1="A2"/>

</Feature1>

Your message came through a bit garbled, but I think what you are trying to do might be best done with either substitution groups or xsi:type.  With xsi:type, you would define:
 
type anyHotel
type hotel1 derived from anyHotel
type hotel2 derived from anyHotel
element property1 of type anyHotel
 
then the instance would contain something like
 
<property1 xsi:type="hotel1" name="H1" address="A1"/>

Is there a way to define multiple types for an element?

For example

 ...

but if I want an XML like below:

 

<Feature1>

     <property1 name="H1" address1="A1"/>

     <property1 name="H2" address1="A2"/>

</Feature1>

 

How can I define XML Schema? Basically I want one property element to have hotel1 as type and other one as hotel2. Is there a way to do such things? If so could somebody please mail me a Schema which does that.
