It would be nice if there was a mechanism defined that could
transfer binary-valued (non-string) attribute values, such as avatar
'icon' images, as OpenID AX attribute values.  This is currently
forbidden by section 3 of AX protocol, IIRC.  I suggest that if such a
binary transfer mechanism were defined, then it could be leveraged
for transferring strings which contain illegal string value characters,
such as newline.
