Как запустить скрипт XQuery для файлов XML с явной информацией о схеме с использованием xqilla?

Я использую xqilla для запуска сценариев XQuery для файлов XML:

$ more BookstoreQ.xml
<?xml version="1.0" ?>

$more query
let $doc := .
for $node in $doc/Bookstore/*
where $node/@Price < 90 and $node/Authors/Author/Last_Name = "Ullman"
return $node/Title

$ xqilla -i ../BookstoreQ.xml query
<Title>A First Course in Database Systems</Title>
<Title>Hector and Jeff's Database Hints</Title>

Вышеприведенное не работает, как только я раскомментирую блок схемы в BookstoreQ.xml:

$ xqilla -i BookstoreQ.xml query
:0:0: error: Error parsing resource: file:///Users/user121/BookstoreQ.xml. Error message: internal subset is not allowed when reusing the grammar [err:FODC0002]

Есть ли способ это исправить?

Какие альтернативные инструменты XQuery имеют CLI?
