schema def must have DESC '' - close paren must be preceded by space
    
    Some of the qmail schema had DESC with no quoted string - for an empty
    DESC, the string must be specified as ''
    For the multiline schema definitions, the close paren must not be the
    first char on the line because that violates LDIF line wrapping - add
    a space before the close paren
