=head1 NAME
XML::XPath::Literal - Simple string values.
=head1 DESCRIPTION
In XPath terms a Literal is what we know as a string.
=head1 API
=head2 new($string)
Create a new Literal object with the value in $string. Note that " and
' will be converted to " and ' respectively. That is not part of the XPath
specification, but I consider it useful. Note though that you have to go
to extraordinary lengths in an XML template file (be it XSLT or whatever) to
make use of this:
Which produces a Literal of:
I'm feeling "sad"
=head2 value()
Also overloaded as stringification, simply returns the literal string value.
=head2 cmp($literal)
Returns the equivalent of perl's cmp operator against the given $literal.
