Given the following class:

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlRootElement;

import org.eclipse.persistence.oxm.annotations.XmlPath;

@XmlRootElement
public class FooBar {
    @XmlAttribute
    @XmlPath("test/@foo")
    private boolean foo;
}

The following incorrect schema is generated:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:ns0="http://moxy.test" xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="http://moxy.test" elementFormDefault="qualified">
   <xsd:complexType name="fooBar">
      <xsd:sequence>
         <xsd:element name="test" minOccurs="0">
            <xsd:complexType>
               <xsd:sequence/>
               <xsd:attribute ref="ns0:foo"/>
            </xsd:complexType>
         </xsd:element>
      </xsd:sequence>
   </xsd:complexType>
   <xsd:element name="fooBar" type="ns0:fooBar"/>
   <xsd:attribute name="foo" type="xsd:boolean" use="required"/>
</xsd:schema>

WORKAROUND:

If we remove the @XmlAttribute Annotation:

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlRootElement;

import org.eclipse.persistence.oxm.annotations.XmlPath;

@XmlRootElement
public class FooBar {
    //@XmlAttribute
    @XmlPath("test/@foo")
    private boolean foo;
}

Then the correct XML schema is generated:

class org.eclipse.persistence.jaxb.JAXBContext
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:ns0="http://moxy.test" xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="http://moxy.test" elementFormDefault="qualified">
   <xsd:complexType name="fooBar">
      <xsd:sequence>
         <xsd:element name="test" minOccurs="0">
            <xsd:complexType>
               <xsd:sequence>
                  <xsd:element name="@foo" type="xsd:boolean"/>
               </xsd:sequence>
            </xsd:complexType>
         </xsd:element>
      </xsd:sequence>
   </xsd:complexType>
   <xsd:element name="fooBar" type="ns0:fooBar"/>
</xsd:schema>
