Hi, I am trying to map a composite key from a different CDT to another one

Hi,
I am trying to map a composite key from a different CDT to another one using one unique key inside xsd. How do I do it? Two columns from one cdt form a composite pair and I have another foriegn key coming from that table which defines the relationship. I want to map this foriegn key to that parent table inside CDT. What all JPA annotations should I use to get this behavior. I tried my best looking up online and troubleshooting with various things like @EmbeddedId, @Embeddable,@XmlInverseReference(mappedBy="fk_key")....but none of them parsed through appian cdt parser. Any help would be deeply appreciated.
