Unfortunately, we usually control only one end of a Web interaction.
And if we're writing a robust Web-crawler, we have to deal with all the
pathological servers and URIs that are out there.

(There's a reason that HtmlPrag was the first library I wrote as I was
starting to learn Scheme: I think permissiveness and recovery is crucial
when we're dealing with the whole Web.)

Sadly, as you know, much of the Web is not standards-compliant. :)
