XML from XSD make errors

I am trying to create an XML file based on an XSD file,The schema definition found in the following link

Schema-http://xmlgw.companieshouse.gov.uk/v1-0/schema/forms/CompanyIncorporation-v2-6.xsd

And my XML is as follows,

   <?xml version="1.0" encoding="UTF-8"?>
  <CompanyIncorporation xmlns="http://ift.tt/1oDa3aN" xmlns:xsi="http://ift.tt/ra1lAU" xsi:schemaLocation="http://ift.tt/1oDa3aN http://ift.tt/Uf6pZ7">
    <CompanyType>BYSHR</CompanyType>
    <CountryOfIncorporation>EW</CountryOfIncorporation>
    <RegisteredOfficeAddress>
    <Premise>38</Premise>
    <Street>Vaughan Road</Street>
    <Thoroughfare>Pentwyn</Thoroughfare>
    <PostTown>Harrow</PostTown>
    <Country>GB-ENG</Country>
    <Postcode>HA1 4EE</Postcode>
    </RegisteredOfficeAddress>
    <Articles>BESPOKE</Articles>
    <RestrictedArticles>false</RestrictedArticles>
    <SameDay>false</SameDay>
    <SameName>false</SameName>
    <NameAuthorisation>false</NameAuthorisation>
    </CompanyIncorporation>

But it will create an error when i validating it,

Not valid.
Error - Line 15, 18: org.xml.sax.SAXParseException; lineNumber: 15; columnNumber: 18; 
cvc-complex-type.2.4.a: Invalid content was found starting with element 'SameDay'. One 
of '{"http://ift.tt/1oDa3aN":Appointment}' is expected.
