This is not a CXF bug but is a JAXB bug. I've gone ahead and logged an issue
with them:
http://java.net/jira/browse/JAXB-858
> xjc generates no JAXBElement for nillable element with required attribute
> --------------------------------------------------------------------------

> Project: CXF
> Issue Type: Bug

> Please consider the following schema:
> {quote}
> <?xml version="1.0" encoding="UTF-8" ?>
> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
> xmlns="http://www.example.org"; targetNamespace="http://www.example.org";
> elementFormDefault="qualified">
> <xsd:element name="root">
> <xsd:complexType>
> <xsd:sequence>
> <xsd:element name="eal" nillable="true">
> <xsd:complexType>
> <xsd:simpleContent>
> <xsd:extension base="xsd:string">
> <xsd:attribute name="att" type="xsd:string" use="required"/>
> </xsd:extension>
> </xsd:simpleContent>
> </xsd:complexType>
> </xsd:element>
> </xsd:sequence>
> </xsd:complexType>
> </xsd:element>
> {quote}
> Running this through xjc generates a member {{eal}} of type {{Root.Eal}} in
> {{Root}}, not of type {{JAXBElement<Root.Eal>}}.
> This makes it impossible to unmarshal a document like
> {quote}
> <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
> <root xmlns="http://www.example.org";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
> <eal att="j" xsi:nil="true"/>
> </root>
> {quote}
> and obtain the value for attribute {{att}} in {{eal}}, since {{eal}} is null.
> The above XML document cannot be represented in the classes generated by xjc.
