org.xml.sax.SAXParseException: s4s-att-invalid-value: Invalid attribute value for 'targetNamespace' in element 'schema'. Recorded reason: cvc-datatype-valid.1.2.1: 'xri://$xrd*($v*2.0)' is not a valid value for 'anyURI'.

error during "discovery" process. 
I'm using "http://me.yahoo.com/rpriyanka_1011" as openid url for testing purpose.
Also I'm running my application from localhost and currently it doesn't have a domain name.
Could that be a reason for failure in 'discovery" process?
