In the case where a web service is returning a response similar to the
following:

<ns1:searchMidbWSResponse ... >
< ns1:return>
< ns1:Site>
<ns2:PropOne>...</ ns2:PropOne>
< ns2:PropTwo>...</ ns2:PropTwo>
etc...
</ ns1:Site>
</ ns1:return>
</ ns1:searchMidbWSResponse>

Notice that all of the Site property elements belong to a different namespace
(alias=ns2) whereas the outer elements belong to the namespace with the ns1
alias. It looks like EDS cannot handle child elements belonging to a different
namespace.
