API IXWireEnd - Wire_End ID

Hi,

     When I look at an exported design in xml format, for the wire tag, I have some children, like, Connection, wireend, property.

     So, under the wireend tag, I have the wire end attribute.  I saw, the wireend have the attribute "wire_end" with value 1 or 2.  So, Thru the API IXWireEnd, I would like to be able to retreive this value.  Like myWireEnd.getAttribute("wire_end") (I try it.. doesn't work).  Is there a way to get this information? with a IXWireEnd object or any other object?

Regards,

Eric
