How to pass XML payload to HTTP POST Service.

Question

Hi All,
I am calling a RestFul service using Http Post method.
If the payload type is "url-encoded" then my directly assignment of values using assign activity is working fine.
But when i change the payload type to "xml" , It's erroring out saying the value is not provided for the parameters..
You can also try this using below details to reproduce the issue.
Details:
=====
URL : http://api.geonames.org/postalCodeSearch
Used HttpBinding as reference in composite.
XSD :
<?xml version= '1.0' encoding= 'UTF-8' ?>

<xsd:element name="postalcode" type="xsd:string"/>
<xsd:element name="username" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
We need to send following input values to the service.
postalcode = 90110
username =siddhardha
Can someone let me know how to make it work with XML payload.Looks like i am not constructing the XML payload correctly in assign.
Please send me the sample to [email protected].
Thanks in advance,
Siddhardha.
