As best I understand it, WS-Security provides a framework for exchanging /
negotiating security-related information, and SAML would describe one
particular type of payload for WS-Security messages, i.e. those that make
assertions about identity, authentication, authorization, etc.  They are
definitely complementary, not competitive: WS-Security talks about SOAP
headers and provides a generic security processing model; SAML doesn't know
anything about SOAP but knows a lot more about the details of security
