    Until cayenne gets true support for JDBC 4 XML types, you should have
    a look at ExtendedType. I am using ExtendedType to map java geometries
    and even colors to text and blob in the database. It should not be
    hard to write such a ExtendedType for XML if you need it.

    Here is the example on how to create an ExtendedType to map geometries.

    Hope it helps.
