Xmltype.transform() with stylesheet that includes another stylesheet

Question

I' trying to use xmltype.transform() with a stylesheet that includes/imports another stylesheet. But this results in a 'ORA-03113: End of communication channel'. Is xsl:include or xsl:import supported?
This is the first stylesheet:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:import href="company2.xsl"/>
     <xsl:template match="/">
          <xsl:apply-templates select="company"/>
     </xsl:template>
</xsl:stylesheet>
And this the second stylesheet:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
     <xsl:template match="company">
          Company: <xsl:value-of select="."/>
     </xsl:template>
</xsl:stylesheet>
Both stylesheets are stored in the Oracle XDB Repository in folder '/public/test'.
The following script results in an error:
declare
l_xsl xmltype;
l_xml xmltype;
l_xml2 xmltype;
begin
l_xsl := xdburitype('/public/test/company.xsl').getxml();
l_xml := xmltype('<company>Oracle</company>');
l_xml2 := l_xml.transform(l_xsl);
end;
I tried the following values for the href attribute of xsl:include:
company2.xsl
/public/test/company2.xsl
http://<host>:<port>/public/test/company2/xsl
I also tried to use xsl:import instead of xsl:include with the above attribute values for href. In all cases I get the ORA-03113.
Thanks for any help, hints or tips.

Did you look in the database alert log or in the database log area to see if any trace file was generated by your error? The listener.log may have more information too.
Also, you can trace your session to see what is happening.
alter session set sql_trace = true;
run sql
alter session set sql_trace = false;
or
alter session set events '10046 trace name context forever, level 12';
or TURN on TRACING for any SESSION
execute sys.dbms_system.set_sql_trace_in_session -
(sid => &sid, serial# => &serial#, sql_trace => true);
run sql
execute sys.dbms_system.set_sql_trace_in_session -
(sid => &sid, serial# => &serial#, sql_trace => false);
