Ryan, I'm not convinced this is the right thing to do, but this is worth
exploring a bit, and certainly worth documenting.

Let's take this in two directions.

1. Document any vendor-specific "X-" support for vCard on the vCard
implementations page (similarly for iCalendar):


2. Add your proposed thoughts on having "hCard to vCard converters optional
produce X- properties" to hCard brainstorming, perhaps in a new section at
the bottom.
