Say I've got an address like this:
Foobar Widget Team
c/o ACME Widgets Inc.
123 The Drive
Someplace Town
BN1 1AB
I want to mark this up as an hCard but I am not sure what class names I should apply to the two organisation names. Foobar Widget Team might be a group of employees who get together and run a local football team, supported and sponsored by ACME but not officially an organisational unit of ACME - they're just using ACME as the mailing address.
So what is the best way of expressing this using hCard? I thought of using the AGENT property, but that seems to apply to a person rather than an organisation acting on behalf of another. Organization-unit isn't quite right either as, strictly speaking, Foobar Widget Team isn't a unit of ACME. How else might I mark this up?
