Create a default Content button behaviour

Hi,

I was using the create default button to generate a sample xml from referred xsd in SOAP UI 4.5.1 free version
I noticed that if i refer to an xsd with namespaces it work.But if i refer to the xsd EnrollRequest.xsd placed inside loyalty folder it does not work.The button is disabled.
As i the interface didnt allow me to attach xsd i am giving the content below.

<grammars>
<include href="./loyalty/EnrollRequest.xsd"/>
</grammars>

<request>
<representation mediaType="application/xml" element="EnrollRequest"/>
</request>

Content of EnrollRequest.xsd

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