Using hypermedia to enable a publisher to expose a URI's structure is
perfectly Web friendly of course.  And I admit to not reading the
entire resolution spec, but it was this paragraph of 11.2 that set off
alarm bells for me because it doesn't prescribe using any
authoritative information in determining whether an http URI is an
HXRI or not.

"URI processors that recognize XRIs SHOULD interpret the local part of
an HTTP or HTTPS URI (the path segment(s) and optional query segment)
as an XRI provided that: a) it conforms to this ABNF, and b) the first
segment of the path conforms to the xri-authority or iauthority
productions in [XRISyntax]."

If that paragraph is incorrect/incomplete, then I stand corrected.
