I find it hard to imagine that embedding such a thing in each downloaded font would be a desirable deployment mechanism. Rather, the vendors (designers, developers, whatever...) offering web fonts ought to be offering boilerplate XHTML/CSS *alongside* the deployable font file itself, as part of the overall package provided to customers. But leaving that aside....

This sounds to me like something that goes way beyond what people would reasonably expect to express in a generic key-value pair metadata form. Also, to be widely useful, it ought to be given a standard, defined place in the metadata spec. As such, it could easily be defined (e.g., in WOFF metadata version 2.0) as a new <sample-xhtml> element that directly includes the relevant XHTML fragment. This is NOT what the key-value metadata extension mechanism is intended for, and we wouldn't want UAs cluttering their "Show Font Info" panel with it anyway.
