The RFC says it means "eXtended" and seems to suggest that these may
go on being x- types forever without standardization.
'The types defined by this document can be extended with private
types using the non-standard, private values mechanism defined in
[RFC 2045]. Non-standard, private types with a name starting with
"X-" may be defined bilaterally between two cooperating agents
without outside registration or standardization.'
If we're waiting for Apple to propose X-AIM as an addition to the
RFC, I suspect we'll be waiting for a long time. I'm not clear on
what harm might come from adding x- class names to vcards. Don't
tools just ignore types they don't understand?
