Surprising generation of Option[String] properties for class from—I thought—required XML elements. The goal is to require all four elements but not in any particular order.

scalaxb xs:all

    <xs:complexType name="NewSshServer">
        <xs:all>
            <xs:element name="uuid" type="xs:string"/>
            <xs:element name="hostname" type="xs:string"/>
            <xs:element name="username" type="xs:string"/>
            <xs:element name="password" type="xs:string"/>
        </xs:all>
    </xs:complexType>

case class NewSshServer(uuid: Option[String] = None,
  hostname: Option[String] = None,
  username: Option[String] = None,
  password: Option[String] = None)
