[Xerte] Editing products of templates?

[jventola at verizon.net]

Executive Summary: After I make a lesson with a wizard (template?) how do I edit it in full 
Xerte and merge it with another lesson?

I finally got around to exploring the Xerte install folder and discovered 
Wizard/pageTemplates.xtp.  Wow. Wonderful.  Where has this been all week?  With this 
wizard, I can do just about everything I need including a quiz with individual feedback.  
Brilliant. 

But I do not understand templates in Xerte.  I need an overview.  Usually, you load a 
template and use it to make and save a new document (as in Word) and the resulting doc is 
editable in the application software.  So  I would have expected to end up with an rlo file that 
I could then open in Xerte.  But the template interface can only save another template. 
(That's bearable since I can just publish it or package it.)  But, say I want to change a 
propety like streaming or loop or play on the sound.  I cannot load the file into Xerte except 
as a template and that template may not offer the option.  If I close the template, I see 
Xerte, but I do not have my lesson to edit--only the logic of the wizard.

I haven't gotten around to models yet.  Maybe that is how you do it?  And is that how you 
merge stuff created with one template into a presentation begun with another?  Suppose I 
had two templates, each of which makes doing something I want in one lesson easy.  How 
do I manage that?  

Similarly, what are all the filetypes of Xerte?  In the Xerte folder I see ico files for rlo, rla, 
rlm, and rlt--not to mention xlm and xwd. And the pageTemplate is an xtp file.  Is this 
explained anywhere?  

Thanks again for the help.
