Yes, well I tried adding something like this:
<wsdl:types>
<xsd:schema
targetNamespace="http://bioinformatics.holstegelab.nl/retrieve_integromics_data";>
<xsd:complexType name="retrieveDataInput">
<xsd:sequence>
<xsd:element name="datatype" type="xsd:string" default="type" \>
<xsd:element name="species" type="xsd:string" default="species" \>
...etc
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
</wsdl:types>
with several different options like: default="..", minoccurs="0",
nillable="false" etc...but nothing seems to work.
My preferred solution at this point would be to have a way to add
default values and if I add the wsdl:types tag to the current wsdl file
do I also need to modify the portType, binding and service tags??
