doc('') stopped working in p:xslt

[AirQuick]

In XSLT, doc(''), which is working fine on 1.3.2-100, does not work on 1.5.4-100:

$ cat pipe.xpl 
<?xml version="1.0"?>
<p:declare-step version="1.0" xmlns:p="http://www.w3.org/ns/xproc">
  <p:input port="source">
    <p:empty />

  <p:xslt>
    <p:input port="source">

        <test />
      </p:inline>
    </p:input>
    <p:input port="stylesheet">
      <p:document href="test.xsl" />
    </p:input>
    <p:input port="parameters">

    </p:input>
  </p:xslt>
</p:declare-step>

Ugh. I'll take a look. All that base uri/document uri stuff is a bit awful.

Fascinating. 1.5.3-100 works fine, 1.5.4-100 doesn't and it is not at all obvious how the changes could have this effect.

[ndw]

Fixed in 1.5.5. The real culprit was a bug in XML Resolver so 1.5.5-100 really only updates the version of the resolver. If you continue to have problems, make sure that you arrange the classpath so that XML Resolver 5.1.3 is used, not the version referenced from the Saxon release.

@ndw : I see that 1.5.5-100 has XML Resolver 5.1.3 in the lib directory and refers to 5.1.3 in the manifest. However, 1.5.5-110 still has XML Resolver 5.1.2 in the lib directory and refers to 5.1.2 in the manifest. Is that what you intended?

[ndw]

Uuuugggghhhh. No, that's a complete fail on my part. And one I can't explain. I guess 1.5.6 is coming up...

[ndw]

Right. I've published 1.5.6 which fixes this error. Sorry about that.

[galtm]

Thanks a lot! Version 1.5.6-110 indeed behaves as expected in the situation where I had seen the problem.
