Re: Quick schema queries

[Mal Lansell <mal@xxxxxxxxxxx>]

Oh, sorry - when I read "\n" I thought you meant chr(10). 
Writing "\n"
in full - chr(92)chr(110) - is fine.

'{' and '}' are valid characters in values without any escaping - the
email discusion concluded that chr(10){chr(10) was always the way that
the structural version would appear in a message.
