They are unnecesary in XML - why have invisible codes when you can substitute <formfeed/> or <bell/>. 2. They can be useful in streamed XML as a record separator - e.g.: <message> ... </message> ^L <message> ... </message> ^L etc. This sort of stream is dead easy to process with Perl's XML::Parser, for example, where you can just set the "StreamDelimiter" variable to ^L and the parser does the right thing. -- <Matt/> Fastnet Software Ltd.
