No, it's a stray '}'. Just delete it. If you've ever looked at the source 
files, they're chock full of square and curly brackets (mainly because the 
other delimiters that Scribe allowed appear in too much Ada text to use them 
frequently -- Scribe doesn't have a quoting mechanism, rather it has six 
pairs of delimiters, and you have to put a pair that isn't used in the 
actual text. Yuck.) So these happen periodically, and syntax is the worst 
(since it uses ] and } and ) and might use >, or " or '). I haven't yet 
found something that uses something from all six pairs, but it wouldn't 
surprise me if I did.

Anyway, it's best to send these sorts of comments directly to me (using the 
agent e-mail) or to the Ada-Comment list. Best not to hope I find them 
somewhere else.
