The "format=t,l" statement tells the server how many octets to use to
encode/decode the vendor "type" and "length" fields in the attributes.
The default is "format=1,1", which does not have to be specified. For
USR VSA's, the format is "format=4,0", for Lucent VSA's it's
"format=2,1", and for Starent VSA's it's "format=2,2".

The supported values for the number of type octets (i.e. the first
digit) are 1, 2, and 4. The support values for the number of length
octets (i.e. the second digit) are 0, 1, and 2. Any combination of
those values will work.

+You can also use "format=Extended-Vendor-Specific-1", through
+"format=Extended-Vendor-Specific-6". These define VSAs in the
+"extended vendor-specific" space.
