Answer 1

If you use EclipseLink JAXB (MOXy) then you can leverage the @XmlPath extension for this (I'm the MOXy tech lead):

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;

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

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class SlideText extends Slide {

    @XmlPath("layout/text/text()")
    private String  text;

}

Using standard JAXB you could leverage an XmlAdapter:

Answer 2

Add a new class Layout:

public class SlideText extends Slide {
    @XmlElement
    private Layout layout;
}

public class Layout {
    @XmlAttribute
    private String  text;
}
