Two possible reasons:
1. 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.
