We have been addressing such problems with more or less working 
solutions in our educational stacks for some time.
I  recognized  the potential of your  flexible approach and appreciate 
it. I was going to comment on it in my last post and then somehow left 
it out.

One of the many areas in which I still have to develop my abilities is 
surely dealing with Regex expressions. I am working on it.

Thanks for the offer, maybe I will come back to that. -

When I said

"At least it is easier to understand and apply than Regex expressions, 
especially for
 Xtalk novices"

I was more thinking of the students at our institution that I try to 
introduce to multimedia programming including using Metacard/Transcript 
when I talked of "novices".

You can inspect some of the results of my endeavors on page "Student 
Samples" of my website <http://www.sanke.org/MetaMedia>.
