I would like to see some indication that the page isn't well-formed
Yes, and iCab does that, by putting a little smiley-face/frowny-face icon on the location panel. Of course, it's always frownyface on PerlMonks, so you can press it to get the errors. Here are the errors for this page as I type this:

I'm still trying to work with the Everything-engine people to get them to put the right ampersand escaping in URLs. Most of the rest of that goes away if you start using CSS instead of explicit tags. But there's still the odd things, like unquoted parameters, for which all we can say is "sloppy coding, please fix up!".

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • Outside of code tags, you may need to use entities for some characters:
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
