I'm sorry but this example doesn't make sense to me. I asked for an example of a HTML page that couldn't be expressed in polyglot and you gave me a google search. I suppose there's some design pattern "SIFR" which produces pages that cannot be expressed in polyglot? 

I'm looking for the report of the XML/HTML reconciliation task force to either explain the difficulty or explicitly reference an explanation. *Why* can't "SIFR" be served as application/xhtml+xml?

The SIFR method would be a common-enough example:

http://www.google.com/search?q=sifr+image+replacement

SIFR fails when served as application/xhtml+xml.  I don't see image
replacement going away any time soon, as WOFF (unlike EOT) requires the
user-agent to download the entire font as opposed to the limited number
of glyphs required for a site's headings (in many cases).  Too much
latency is added on landing pages vs. using image replacement.

The newer Facelift image replacement method works polyglot, though, so
SIFR serves only as an example of in-the-wild failure, not as an example
of something which *cannot* be done.
