I wouldn't have thought it made any sense to have a default value for an element, since elements don't have values. A default value for an attribute would make sense, but that isn't what you are trying to do there. Actually I am not sure what you are trying to do.

Thanks a lot , but i am just searching and got to know this from w3schools website and not sure how this works

http://www.w3schools.com/schema/schema_simple.asp

   
Default and Fixed Values for Simple Elements

Simple elements may have a default value OR a fixed value specified.

A default value is automatically assigned to the element when no other value is specified.

In the following example the default value is "red":

<xs:element name="color" type="xs:string" default="red"/>

A fixed value is also automatically assigned to the element, and you cannot specify another value.

In the following example the fixed value is "red":

<xs:element name="color" type="xs:string" fixed="red"/>

I would suggest getting a proper learning resource for XML Schema. There are a lot of Internet sites which post reference information about various things but most of them don't have much information beyond that. W3schools is one of those. You can't learn Schema from brief descriptions of its features.
