Comparing SPKI with X.509 is like comparing apples and speedboats. 

In spite of its name, SPKI is NOT a PKI and does not allow a PKI to
be built with it. Neither with SDSI, in SPKI/SDSI. 

Further, SPKI addresses the question of "what" and only to the issuer
-- while X.509 addresses "who" and "what" and not only to the issuer.

Further, as a general rule, it is not advisable to set goals of what
you want to demonstrate before studying the subjects -- because the
subjects may not be even comparable, as the case at hand..
