Hi Asir,

I don't grasp how RFC 3987 pertains to establishing a base URI. Could 
you point me to the relevant section(s) in the RFC?

Applications and specifications built upon these new technologies will natively support XML Base." [1] XML Information Set specification has a normative dependency on XML Base [2]. Any specification built upon XML Information Set will natively support XML Base. Web Services Policy is built upon XML Information Set. So, it doesn't hurt to explicitly call out the support for XML Base.
