<para>Since Unicode supports character positions higher than 256, a
- representation of those characters will obviously require more than
- one 8-bit byte. There is more than one system for representing
- Unicode characters as byte sequences. UTF-8 is one such system. It
- uses a variable number of bytes (1 to 6) to represent each character.
- This means that the most common characters (ie: 7 bit ASCII) only
- require one byte.</para>

+ <para>When your document is too large to slurp into memory, the DOM,
+ XPath and XSLT tools can't really help you. You could write your own SAX
+ filter fairly easily, but Michel Rodriguez has written a <ulink
+ url="http://www.perlmonks.org/index.pl?node_id=429707">general
+ solution</ulink> so you don't have to. You'll find it bundled with XML::Twig
