xalan 1.1 document() fails on url?

Can someone confirm for me that the document function in 
xalan j 1.1 and >  chokes inappropriately on http URIs?

This: 
<xsl:apply-templates select="document('http://www.heml.org')"/>

or anything like it generates:
Transforming...
http://www.heml.org; Line 5; Column 48
XSL Warning: Can not load requested doc: http://www.heml.org

whereas a file runs through tickety-boo.

(You might think that functionality is just not implemented yet, but the 
src code clearly uses the java URL class at one point.)
