Illegal PHOTO properties used in CardDAV/put.xml?

[ksmurchison]

Two tests PUT vcards having the following form:

VERSION:3.0
PHOTO;BASE64:...

The PHOTO properties appear to be illegal per v2.1, v3.0, v4.0 by my reading.

The verifier for the test checks for PHOTO;ENCODING=b:... which is the proper for for v3.0

I don't know if the source resource was deliberately written because its been seen in the wild, or if its a simple typo.

Should we fix the source resource to be v3.0 compliant or fix our implementations to accept such a resource?
