p:load can't find missing DTD when not validating against it...

I'm trying to load an XML-file that declares a DTD in its doctype, but the
DTD isn't available. I don't need to validate against it anyway, but the
declaration is there. This doesn't work:


<?xml version="1.0" encoding="UTF-8"?>
<p:declare-step xmlns:p="http://www.w3.org/ns/xproc" xmlns:c="
http://www.w3.org/ns/xproc-step"
    version="1.0">
    <p:input port="source">
        <p:inline>
            <test/>
        </p:inline>
    </p:input>
    <p:output port="result"/>

    <p:store href="test.xml" doctype-public="-//TEST//DTD TEST Test//EN"
doctype-system="test.dtd"/>
    <p:load href="test.xml" dtd-validate="false"/>

</p:declare-step>


Shortened down, this is the error I get:

com.xmlcalabash.core.XProcException: XProc error err:XD0011
at com.xmlcalabash.core.XProcException.dynamicError(XProcException.java:176)
Caused by: net.sf.saxon.s9api.SaxonApiException:
java.io.FileNotFoundException: /home/jostein/Skrivebord/test.dtd (No such
file or directory)

at net.sf.saxon.event.Sender.sendSAXSource(Sender.java:423)
Caused by: java.io.FileNotFoundException: /home/jostein/Skrivebord/test.dtd
(No such file or directory)

So it looks for the DTD, even though I specifically ask it not to validate
against it. Is this correct behavior?
As you can see from the output, I'm using Calabash (CLI reports version
0.9.22 although I think I've installed 0.9.23).
