Question

I have defined a xml schema as below

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

<xs:schema id="PacketTemplate"
targetNamespace="http://tempuri.org/PacketTemplate.xsd"
elementFormDefault="qualified"
xmlns="http://tempuri.org/PacketTemplate.xsd"
xmlns:mstns="http://tempuri.org/PacketTemplate.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:group name="packetTemplate">
  <xs:sequence id="packetTemplateSequence" >

   <xs:element name="packetType" maxOccurs="1" minOccurs="1" nillable="false" >
    <xs:complexType >
      <xs:attribute name="packetCode" type="xs:string" use="required"></xs:attribute>
      <xs:attribute name="packetTypeIncoming" type="xs:boolean" use="required"></xs:attribute>    
    </xs:complexType>
  </xs:element>
  <xs:element name="packetFieldInfo" minOccurs="1" maxOccurs="unbounded">
    <xs:complexType>
      <xs:attribute name="fieldName" type="xs:Name" use="required"></xs:attribute>
      <xs:attribute name="fieldNumber" type="xs:integer" use="required"></xs:attribute>
      <xs:attribute name="conversionCode" type="xs:integer" use="required"></xs:attribute>
      <xs:attribute name="fieldInUse" type="xs:boolean" use="required"></xs:attribute>

     </xs:complexType>
  </xs:element>
</xs:sequence>

now when i write xml file corresponding to this schema i am not able to use intellisense features like it should show all of possible tags in my file?

Beside that what should i do so that this xml file refer the schema file i have defined?
Xml file is as below.

    <?xml version="1.0" encoding="utf-8" ?>
    <packetTemplate>
       <packetType packetCode="601" packetTypeIncoming="123" fieldInUse="true">
       </packetType>
    </packetTemplate>

In Visual Studio you can open the *.xml file and in the properties window you can specify the schema file in the property Schemas.

That way Visual Studio should provide Intellisense, assuming the provided schema is valid.

You can check the W3Schools examples in how to create a XML schema.
