AFAICT, any of "{" | "}" | "|" | "\" | "^" | "`" could be used, except
RFC2396 states that these "...characters are excluded because gateways and
other transport agents are known to sometimes modify such characters, or
they are used as delimiters". However, given that they would be inside an
XML document, would this be an issue?
