Thanks a lot for your answer! Indeed, it pointed me in the exactly right direction. As I found out, it's just as easy as using @XmlElements to surround multiple @XmlElement annotations. :-)
Thank you so much!

Subject: Re: How to get different things into the same list?
You need to tell JAXB to create one list and what to allow inside it.
Here is a snippet of my JAXB parser for COLLADA 3D files that should
help point you in the right direction...
@XmlElementRefs({
@XmlElementRef(name = "matrix", namespace = "
http://www.collada.org/2005/11/COLLADASchema
", type = Matrix.class),
@XmlElementRef(name = "rotate", namespace = "
http://www.collada.org/2005/11/COLLADASchema
", type = Rotate.class),
@XmlElementRef(name = "skew", namespace = "
http://www.collada.org/2005/11/COLLADASchema
", type = Skew.class),
@XmlElementRef(name = "translate", namespace = "
http://www.collada.org/2005/11/COLLADASchema
", type = JAXBElement.class),
})
protected List<Object> transforms;
In this list it is imperative that the elements of "transforms" are
kept in the order defined in the file (otherwise the data is useless);
when using this method JAXB guarantees that this is the case. Use
this as a guide and look at the docs for these elements, that should
get you going.
