Hi Daniel,

Thank you for this thoughtful and detailed message.

I don't think this has anything to do with web architecture. The  
resource "results of validation for http://www.example.com (validated  
with options foo and bar)" is properly identified by a URI, and can  
be bookmarked, mailed, etc. This is different from a lot of scripting- 
heavy sites.

The question here is one of user interface, not of web architecture.
I do understand your concern UI-wise, hence this discussion, however.

I am asking about the way the results are displayed, and specifically  
about the bar at the top with links to particular aspects of the  
results. I reckon this is closer to what you would like to see for  
the CSS validator. Hence my pointing it to you.

This is because of a very long line without any space in the source  
display, making the viewport extremely wide.
It does not generally happen, e.g

That is not a bug, it's a feature. Unlike the source display above,  
the tidied source is there to be copy-pasted, not looked at  
extensively. This is why it is put in a pre, with scrolling overflow,  
to avoid making the global window too large (something you agree is a  
usability problem, see your comment above).

Thank you,
