I'm no expert, but I'm planning to do this. You can use xpointer to avoid a
calling eval (though I don't know whether or not it calls eval under the
covers. https://docs.marklogic.com/xp .
Be aware that all xpath evaluations give access to any document in your
database because /doc("anyDocInYourDB.xml") is valid xpath. So do it only
if your document permissions are *exactly* as you need them.
There may be other security ramifications that I don't know about. It
would be great if someone more knowledgeable chimed in about this.
