Schema import in Energy Interop WSDLs using relative URIs

The energy interop  WSDLs have relative URIs to import EI schemas,  e.g.:

   <xs:import  schemaLocation= ..xsdEiPayloads.xsd  namespace=  http://docs.oasis-open.org/ns/energyinterop/201110/payloads /
>
The path separator  for URIs is the forward slash (RFC 2396),  so it looks this should be  something like:

   <xs:import  schemaLocation= ../xsd/EiPayloads.xsd  namespace=  http://docs.oasis-open.org/ns/energyinterop/201110/payloads /
>
