Why choose SAML v2.0 over SAML v1.1?

If the answer is not very obvious, please follow the following document that highlights the differences between SAML v1.1 and SAML v2.0. The document is called Differences Between SAML V2.0 and SAML V1.1

In a nutshell,
a) SAML v2.0 is a major update to the specification. It includes considerable contributions from the Liberty Alliance ID-FF donations.
b) XML Encryption is supported only in SAML v2.0
c) The following protocols are added or revamped in SAML2.
* Assertion Query and Request Protocol
* Authentication Request Protocol
* Artifact Resolution Protocol
* Name Identifier Management Protocol
* Single Logout Protocol
* Name Identifier Mapping Protocol
