#462 <example> tag and &.

[Chris Kemp]

If you create an <example> tag that contains an &
character then the system will silently fail to
generate any of the <summary> for the entire member.

My code contained the text "Monday & Tuesday" and it
failed to build the <summary>. No error was
reported. It was resolved by typing "Monday &amp;
Tuesday" into the <example>

The system should either report an error when it
encounters an & or should accept it and do the
conversion.

btw, Nice work guys. Like NDoc a lot.
