Generate form letters using cgidev2, docx/xml.

I've perused the list, mainly the contents of this thread
http://archive.midrange.com/rpg400-l/201009/msg00170.html

1. Create your word document and save it as the new DOCX format,
which is just XML.
2. Edit the XML in notepad or whatever you like, and add in
the CGIDEV2 tags for what you want.
3. Copy DOCX file to IFS.
4. Use CGIDEV2 to insert the needed data based on tags you inserted.

I would like to create a docx xml template, then use cgidev2 to open
it and generate some form letters. Some of the resulting letters
will be emailed, others printed.

When I open my template docx file (with docx extension) in notepad the
text is unintelligible.

Is this process not doable? Am i missing a step? any ideas appreciated?
I have tried most 'save as' output options from Word.

Thanks,
John
