yes, there are some cases where it is handy to include additional 
parameters on existing properties. e.g., consider IMPP which is specified 
as a URI for an IM service:

IMPP:xmpp:[e-mail]

Often times, people use arbitrary "display names" (handles) in their IM 
clients, and it would be handy to have those listed in the vcard via a 
parameter on the IMPP property. However, there is no restriction on using a 
DQUOTE in such display names, so we need to allow for DQUOTEs in the 
parameter value.

A similar issue exists for the (now defunct) SOCIALPROFILE property, which 
I still have an interest in using and reviving.

In iCalendar, a good example is the CN parameter (Common Name). Some 
systems allow users to configure their own names so they can add "phrases" 
in the middle, e.g. 'Cyrus "Mulberry Dude" Daboo'. Or perhaps a room or 
resource has a "quoted" title in its name too. So again, there is a need to 
support DQUOTE.
