The message says that your declaration of a function is unexpected.

Sure enough, that isn't an expected place for a function definition.

Reviewing:  http://www.w3.org/TR/xquery/#id-function-calls

And that is pretty explicit that functions can only be declared in the prolog.

You have:

.... which doesn't have the declaration in the prolog, but in the 
middle of the query.

So I think the error message is quite justified.

I hope this helps.
