Each wiki page has a 'Valid XHTML' icon at the bottom.

However, clicking on the icon to display the validation
results displays "This page is not Valid XHTML 1.0
Transitional!".

Sample error for the home page
(http://validator.w3.org/check?uri=http%3A%2F%2Fphpwiki.sourceforge.net%2Fphpwiki%2F):

Line 61, column 35: cannot generate system identifier
for general entity "PHPSESSID"

<a

a php problem, not related to phpwiki.
reload the page again. the php-internal sid will disappear and
the valiadtion will be true.

if you want fully xhtml-conformant pages with some args,
you must set the php arg_separator.output from & to ; or
&
arg_separator.output = ";"

currently phpwiki doesn't use this value, so with certain
options we produce non-conformant links. However, the php
default value was never xhtml-conformant and is used in
99.9% of all installations, so I don't care that much.
