By "professional engineers", do you mean actual licensed PEs, or do you 
mean people who are paid and have a job title of "engineer"?

Is this going to be a course for MITRE folks?  I'm just interested 
because I used to work there (at Bedford and then at McLean).

Whatever else you include -  and I completely endorse Ken Holman's 
experience - "Shouldn't you be asking the students or the people who 
tasked you with teaching them what the desired outcomes should be and 
work your way backward from there to figure out the appropriate topics?" 
- you should include some basic nuts and bolts, like:

- how to check well-formedness (I like RXP, run in a console);
- if someone gives you an XML schema, how to check it for correctness, 
preferably without buying expensive software and probably on the command 
line;
- how to run an xslt transform from the command line;
- how to extract data from an xml file in a program (that's assuming 
that they want to be able to write some xml processing programs).  This 
should cover at least some java and .net methods.  Work hard to make it 
simple!

If you get into xml schemas, I'd show them how different schema tools 
can disagree on validity of some documents with respect to their 
schemas.  Or maybe my experience is too out of date - do these problems 
not arise any more?  It was often a problem for me, back when I was 
still working with them.

Make sure that they have some exposure to unicode, and how they can 
write (and save) xml files in the intended encoding - and don't let them 
stay exclusively with ASCII.  Sounds trivial, but in practice you can 
easily be bitten.  Note that utf-8 in a Windows console can be a 
problem, even if you specify code page 65001, depending on the output.

Something that isn't talked about much but can be very useful - xml can 
be styled with css in a browser.  This can be handy for quickly viewing 
xml data more readably than with an editor.  This would have to cover 
using the stylesheet PI in a document, so that the browser would know 
what stylesheet to use.
