xtags v1.0 parse custom JSP tag using Dom4J Document object parameter

Background:
Trying to parse a Dom4J XML Document using <xtags:parse> in order to iterate through it (XSLT style) inside JSP code.

Problem Description:
The JSP code has an inline Dom4J Document object, however it cannot be passed as a parameter to xtags:parse
eg. when trying:
<%
org.dom4j.Document xmlDoc = ...;
%>
<xtags:parse reader="<%= xmlDoc %>" />

the following error message is occuring:
Explicit cast needed to convert org.dom4j.Document to java.io.Reader._jspx_th_xtags_parse_0.setReader( xmlDoc);

according to the xtags:parse v1.0 API documentation, this is occuring because the reader parameter of xtags:parse requires an object of type java.io.Reader so the question is how to get a java.io.Reader from an org.dom4j.Document (The xtags:parse v1.0 documentation shows how to parse a URL, an XML file, a java.io.Reader etc, but doesn't have an example for an org.dom4j.Document parameter).

Problem Solution:
Kind of straight-forward and ugly but:
<%
org.dom4j.Document xmlDoc = ...;
%>
<xtags:parse>
<%= xmlDoc.asXML() %>
</xtags:parse>
It would have been nicer to have a parameter to the tag that accepts an org.dom4j.Document however the performance doesn't seem to be an issue (ie. with the writing of the XML straight to the output stream).
