[xacml] normative elements,identifiers,algorithms and whether mandatory

[Anne Anderson <Anne.Anderson@Sun.com>]

Attached is a list of all schema elements (16f.xsd), identifiers,
and algorithms.  Within each list, items are in alphabetical
order.  Each item is labelled "M" or " ", meaning "Mandatory to
implement" or "normative, but not mandatory to implement",
respectively.  The list of identifiers includes Michiharu's
additions.

Questions:
1. Should the following elements in the policy schema be mandatory?
   ?  xacml          AbstractDefaults  (abstract)
   ?  xacml          PolicyDefaults
   ?  xacml          PolicySetDefaults

2. Should we include xs: datatypes that we require to be
   supported, or do we assume all of them are mandatory?

3. Does flagging an attribute identifier as
   mandatory-to-implement mean that the corresponding attribute
   is mandatory-to-implement?  (I assume yes)

Please let me know if these are correct.  Tim, if you would like
to have these labelled by the section number in version 15 of the
spec, let me know.
