Some pages do not validate as XHTML 1.1

Using the W3C validator (http://validator.w3.org), it
is found that some pages do not correctly validate as
XHTML 1.1 yet.

Summary of findings:
- In some forms the name= attribute is used instead of
(only) the id= attribute
- an extra form close tag is present in the inbox view
- instances where ampersands in generated URL's are
not urlencoded
- input field has a "bare" checked attribute instead
of the required name/value syntax for that attribute

Detailed output of the W3C validator with hints where
and how to fix, can be found in the attached text file.

Environment:
Windows XP Pro SP2
Apache 2.2.0 with PHP 5.1.2 as module
NOCC 1.3-dev (CVS build 2006-08-28)
