Many annotators invoked when only 2 were specified

Using v0.5.2, I would expect the following code to invoke only the two specified annotators, tokenize and ssplit:

xquery version "3.1";

import module namespace nlp="http://exist-db.org/xquery/stanford-nlp";

nlp:parse(
    "Hello World!",
    map {
        "annotators" : "tokenize, ssplit",
        "tokenize.language" : "en"
    }
)

But judging by the logs, it also invokes pos, lemma, ner, depparse, and coref:
