Marc had mentioned this problem to me privately and I couldn't think of
a solution at the time. Now I think this would be right:

Adapted for vCard 4:

   X-abccompany.TEL;TYPE=work,voice:+1-213-123-4567
   X-abccompany.ADR;TYPE=WORK,PARCEL:;;2nd Street;My
    Town;CA;91921-5678
   X-xyzboard.TEL;TYPE=work,voice:+1-213-555-1234
   X-xyzboard.ADR;TYPE=WORK,PARCEL:;;123 Main Street;Any
    Town;CA;91921-1234

You can replace X-abccompany or X-xyzboard with work if you want to use
its semantics (i.e. "properties related to an individual's work place").

Otherwise, the X- groups have no special meaning that could be
interpreted by a computer. But you can use the X-group.ORG property to
describe the group to a human.

So the example becomes:

   work.TEL;TYPE=voice:+1-213-123-4567
   work.ADR;TYPE=PARCEL:;;2nd Street;My
    Town;CA;91921-5678
   work.ORG=ABC Company
   X-xyzboard.TEL;TYPE=voice:+1-213-555-1234
   X-xyzboard.ADR;TYPE=PARCEL:;;123 Main Street;Any
    Town;CA;91921-1234
   X-xyzboard.ORG=XYZ;Board

Same problem has same solution, e.g.

   X-summer-residence.ADR:...
   X-summer-residence.TEL:...
   X-summer-residence.ORG:Summer residence
