Import XSD to create datatypes

Hello Everybody-

I want to create a datatype that is specific for my outbound message,i have the xsd of that structure,i was trying to import the xsd to form a XI structure.Here is what i have done.

1.Right clicked datatypes and clicked on new

2.It asked me for a name and i gave a name "venkat".

3.Then from menu-tools, i clicked import xsd and selected my xsd. Then i got a message that Schema to be handled does not contain a definition of type venkat.

4.So what i did this time i gave the name as OrderRelease instead of venkat(as stated in step 2) and still i get the error.

I am pasting a snippet of my xsd.

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

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<xsd:element name="OrderRelease">

<xsd:complexType>

<xsd:sequence>

<xsd:element name="MergeNode" minOccurs="0" maxOccurs="unbounded">

<xsd:complexType>

<xsd:sequence>

<xsd:element name="ShipNodePersonInfo" minOccurs="0">

<xsd:complexType>

<xsd:attribute name="Suffix" type="xsd:string"/>
