What you say makes sense.  Thanks for answering my question.  Now for 

You answer assumes I know how to generate the file gnucash-guide.xml.  I 
likely have read past it in the various documents available, but, sad to 
say, as of now I don't recognize the command, script or process that 
generates that file.

Can you point me to it?
