Better than what?    (02)

XACML [1] defines a conceptual framework and concrete syntax for
restricting or allowing access to any resource whatsoever based on
attributes of the resource, the requestor, the action, and the current
environment. What more is wanted?    (03)

When I was on the XACML TC I proposed moving the spec toward better
compatibility with RDF and the semantic web stack. But even in its
present form it is largely interoperable with RDF and other standard
rule languages.    (04)

A company I know wanted to use XACML to provide fine-grained access
control in a COTS application. The COTS vendor said "that won't work, we
won't support it, use ours (for extra $$$)". Company said "prove it".
They couldn't, lost in a bake-off. XACML works just fine.    (05)

General principle: Standardization spells reduced revenue stream for
big software vendors. They will resist it as long as their customers
keep buying non-standards-compliant products.    (06)
