RE: RE: [xacml] another small time/date issue

["Daniel Engovatov" <dengovatov@bea.com>]

To clarify myself:  yes, in most cases it is the PDP that will "provide"
this attributes.  But as we where discussing for quite a while now - I
do not think it is feasible to put exact requirement on exactly how it
is done.
The fact that it is a single block on Figure 1 does not mean it must be
implemented as a monolithic piece in any sense.

Could you suggest an example of a clarification?  Maybe it would be
easier for me to understand why it is a problem then.

Thank you.

Daniel.

If I understand the block diagram in the specification correctly it is
PIP that is responsible for all and any of the attributes.  The source
of this
Information, except for the request context is not specified and left to
the implementation..

It already is. The PDP must supply current time/date
values if they're not included in a request. Unlike
other attributes, these values must always be
available, so in practice most people will use a PDP
that knows how to provide this data directly. This
is why I wanted to see some clarifiaction.
