My PolicyRequest.xsd file

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:p="http://www.example.org/Payment"
xmlns:n="http://www.example.org/Note"
xmlns:c="http://www.example.org/Consent"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">

<xsd:import namespace="http://www.example.org/Payment"
    schemaLocation="Payment.xsd" />

<xsd:import namespace="http://www.example.org/Note"
    schemaLocation="Note.xsd" />

        <xsd:sequence>
            <xsd:element name="Payments" type="p:Payment"
                maxOccurs="unbounded" minOccurs="1" />
            <xsd:element name="Notes" type="n:Note" maxOccurs="unbounded"
                minOccurs="1" />
        </xsd:sequence>
    </xsd:complexType>
</xsd:element>

My wsdl file

In the wsdl file i get

XSD: Type reference 'http://www.example.org/PolicyRequest#PolicyRequest' is unresolved

Why I'm not able to access element from my xsd?

[1] You add the targetNamespace attribute (http://www.example.org/PolicyRequest) to the PolicyRequest.xsd. (It is not there in the xsd as shown.)
[2] In the wsdl:types, you reference that "element" in the imported PolicyRequest namespace rather that via type (because you do not define a named type, but rather a named element there).

        <xsd:element ref="pr:PolicyRequest" />

[3] Similar thing might be happening for PolicyResult as well, but many xsd's are not shown so it is just a deduction by analogy.
[4] By doing the above, effectively, you'r making the http://www.example.org namespace practically empty if that is what you really have in mind.

But as I look through the shown portions of wsdl and xsd and with some logical deductiond on the unshown, I think there are many many places you've to rewrite to make thing really glued together properly.
