I prefer to think of it as ~~Haskell~~-like indentation syntax, if you don't mind.  :)

If you like lisp-ish syntax, take a look at {link:SXML|http://okmij.org/ftp/Scheme/SXML-short-paper.html}.  For a list of other XML shorthands, see the [PXSL FAQs].

(BTW, you can insert code into your comments by wrapping it within \{code\} delimiters.)
