Hi,
My edition has three manuscript sources, and one of them does not include 
many of the paragraphs included in the other two. I am trying to figure out the 
best way to encode these lacunae.  My code follows.  I guess my basic 
question is: I don't like the nested app version, it seems to make it harder to 
do sorting and looping of the data; but I'm also not sure about the lacuna tags 
- I'm just starting to learn XSLT but will it be possible to write something that 
would find the text between a lacunaStart tag and a lacunaEnd tag and then 
do something with it (like exclude it from the display version of that witness on 
the screen).
Thanks!
