URL length is another argument for numeric representation of validation
level. A new AX spec could specify that the response be in the format

NNN:MMM:XXX

where NNN is the numeric validation level, MMM is how many days have passed
since validation, and XXX is the value. AX requests would be no longer 
than in AX 1.0, and responses would grow by very little.

Request (also showing "type" reduced to "t" -- the request/response syntax
is far too chatty given the 2k limit for GET requests):
openid.ax.t.c=http://axschema.org/contact/phone/cell

Response:
openid.ax.t.c=http://axschema.org/contact/phone/cell
openid.ax.d.c=50:707:+1-555-555-1212

or simply the following -- I don't see why the current AX fetch response
echoes the "type" parameter from the request:
openid.ax.d.c=50:707:+1-555-555-1212
