Subject: Re: [sca-bindings] ISSUE-49: UPA in web service binding withEndpointReference



... the alternative being to add an extra wrapper element:

<binding.ws>
  <address>
    <wsa:EndpointReference>
  </address>
</binding.ws>

Re: [sca-bindings] ISSUE-49: UPA in web service binding with EndpointReference





One way to fix this would be to remove the wsa:EndpointReference element
from the schema. The <any> would still allow it to be used. The
wsa:EndpointReference element will be part of the spec but not the schema.
