SOAP vs REST (differences)

I have read articles about the differences between SOAP and REST as a web service communication protocol, but I think that the biggest advantages for REST over SOAP are:

1. REST is more dynamic, no need to create and update UDDI(Universal Description, Discovery, and Integration).

2. REST is not restricted to only XML format. RESTful web services can send plain text/JSON/XML.

But SOAP is more standardized (E.g.: security).

So, am I correct in these points?
