adding unparsed entities

I am transforming a document to TEI.2. TEI.2 requires that graphics
(such as JPEGS) be included using unparsed entities. 

I assume there is no way to really add an unparsed entity to a result
tree (except by using escaping, which I don't like to do). Am I correct?
Has anyone come across this problem?

Thanks

Paul
