Fix one XML validation warning.

[SVN r62708]
Fixed ticket 2672 by applying (and slightly modifying

the attached patch.  The page now seems to validate
correctly.

[SVN r62707]
Tokenizer documentation fixes for ticket 2672.

Applied these changes.

The revision date should be changed from ''25 December, 2006'' to ''9 June
2010''. You could also change the webbot element from ''s-format="%d %B,
%Y"'' to ''s-format="%d %B %Y"''. The comma is superfluous in that format.
