ABAP to asXML to XSLT to XML???

Question

Hi,
I have a few questions concerning <b>Call Transformation</b> hopefully someone has done this before. I am attempting to convert an ABAP internal table to a particular XML layout for consumption by an external application.  There seem to be a few options available to accomplish this and I have read tons of examples and threads.  I would prefer to use option 2 but I cannot find a way to apply the XSLT transformation. Why would anyone implement an XML class and not provide a transformation method???  Anyhow, the options seem to be...
1. CALL TRANSFORMATION
OR
2. cl_xml_document
The code below utilizes the Call Transformation option.  The first transformation converts the internal table to asXML (I think that is what it is called).  The second transformation utilizes XSLT to render the asXML to a final XML structure.
My Questions:
1.  Can I convert the internal table directly to the final structure of XML utilizing XSLT via Call Transformation?
2.  How can I output the resulting XML in xml_out2 to a file share?  I have tried using the if_ixml_ostream interface.  This does not seem to work, I can only write to the servers home directory and I get an empty root node.  This despite the fact that only one thing has changed in my code
CALL TRANSFORMATION (`ZXSLT02`)
SOURCE XML xml_out
RESULT XML xml_out2.
Changes to
CALL TRANSFORMATION (`ZXSLT02`)
SOURCE XML xml_out
RESULT XML xml_outStream.
I ask that if you respond please provide specific examples/solutions. Like I said before, I have read nearly all documentation and examples docs. They all seem to take you the cusp of a solution and then leave you short with no specific working examples. The below code and XSLT can be run in the ABAP workbench as  working runnable code. It would be great to receive input referring to working runnable solutions.  I thank all for the time and efforts...

O.K. Here is what I evenually came up with...
You should be able to cut, paste and run all below providing you replace the path specified with
<server Name>\<folder name>.  Disclaimer: <i>I am not sure what version of Web AS, ABAP or basis this requires.</i>

END   OF person.
DATA : it_person TYPE STANDARD TABLE OF person,
       wa_person LIKE LINE OF it_person,
       xml_out TYPE string,
       icount TYPE i.
*Build the Internal Table
DO 5 TIMES.
  PERFORM addperson USING icount CHANGING wa_person.
  icount = icount + 1.
