It's nicely presented but I agree with Michael Kay that some essential
information is missing: what proportion of the documents were XHTML/HTML
and/or RSS?

In addition, as Michael Kay again noted, it's not an error for a
schemaLocation hint to fail to resolve; furthermore, it's common
(normal, in fact) for an XML document to be valid against a schema (XSD
or RNG) without actually mentioning that schema explicitly.

As for the authors' thesis that "high quality" XML is necessary for
XQuery In The Browser to be useful, I think the same applies to XSLT
(e.g. SaxonCE), and in fact by operating on the browser's DOM it's
presumably much lss of an issue in practice. After all, given the
common-origin restrictions in Web browsers, the people using XQIB on the
XML documents in the browser are presumably the publishers of the XML,
so if it doesn't work for them, they'll fix it, no??
