Only to be sure about that: did you declare the namespace? You would
do that by adding the line

declare namespace sawsdl="http://www.w3.org/ns/sawsdl";

As an alternative you could use the query

for $x in doc(\"aa.wsdl\")/wsdl:definitions/wsdl:types/xsd:schema/xsd:complexType
return <node>{$x/@*:modelReference}</node>

which looks for attributes "modelReference" in all namespaces.
