Thanks a lot. I added the function to the CVS and the snapshot release.

getDependency() should only return the default setting:

Dependency.CONTEXT_SET | Dependency.CONTEXT_ITEM;

This indicates that the function should be called once for every item in the 
context. eXist has some optimized functions (e.g. fn:not) that are able to 
process the entire context in a batch. However, for most functions this 
doesn't apply. The same is true for inPredicate, which is only relevant for 
optimized functions.
