BPM issue in NWDS deployment

Hi,

I have made a BPM scenario in NWDS.

In BPM deployment from NWDS i am getting error.

I have imported  few service interfaces and one xsd file. The xsd file of ESR is coming without namespace in NWDS.

The error is :

ParseError at [row,col]:[1,212]
Message: http://www.w3.org/TR/1999/REC-xml-names-19990114#EmptyPrefixedAttName?prefix="xmlns",localpart="ns1",rawname="xmlns:ns1"

Can you please help in it ?

Regards
