I think making a general statement that 'SSL is not secure for web 
services' is not quite accurate. There are certain deployments/usage of 
Web services (which perhaps may be quite common) where SSL does not fit 
the bill.

SSL being point-to-point provides security at the connection level, but 
does not provide end-to-end security.

Consider a message that traverses several hops (which use the same or 
different transport). In such a case SSL does not provide you with 
message integrity.
Another example is: the payload of the message is stored in a queue and 
processed at some later point in time.

WRT to intermediaries there can be transport intermediaries or SOAP 
intermediaries [1].
