Another option would be to integrate this with the publisher itself.
For example, an option could be provided for validating the HTML to be
returned by the publisher whenever it's running in validating mode,
similar to debug mode.  It seems like this could make the validating
service more accessible to less technical users.  I'm not really sure
where this belongs.
