To be sure I understand, this text (2 denotes hex two, 3 denotes hex three):

    2Hello World3

is converted to this XML:

   <text>U2XHello WorldU3X</text>

Is that the approach Liam? 

Have you documented this approach anywhere?

Another is to use an escaping mechanism - e.g. what I call "UCODE", in
which an upper-case "U" is followed by hexadecimal and a trailing X to
mark the end; this can safely be used in XML element names for example.
