Integer value in a variable of assing action is no more integer - OSB

Question

Hi,
I have seen a strange behavior or I wonder am I missing anything in OSB assing action.
I am developing a simple proxy service in 11.1.1.6 OSB.Following are the steps involved in my code.
In first assign action, the value is assigned as xs:integer(1) to a varible varTest
Next, I've added an if condition as below.
        if( $varTest != xs:integer(0))
        then
        assing "success" to $varResult
While testing the PS using the test console,  I've got the following error at if condition.
line 1, column 14: {err}FOTY0012: Items not comparable: types are "{http://www.w3.org/2001/XMLSchema}string" and "{http://www.w3.org/2001/XMLSchema}integer"
This error is fixed after changing the if condition as below.
  if(xs:integer($varTest) != xs:integer(0))
Ideally varTest should contain value of type integer right?
Is it kind of a bug or am I doing any mistake?
Could you help me out.

Hi Abhishek, Eric,
Thanks for your reply.
It is clear that  OSB's native data format is XML.
It should also support simple XML types right?
Even, when we create a new variable structure form OSB console, we can see String as simple type( I could not see other simple types) along with element types based on either schema or WSDL message.
Can I consider this as a limitation of OSB?
