[sunxacml-discuss] Namespace in RequestCtx.encode and target/condition functions in FunctionFactory

[Jie R. <ji...@ic...>]

Hi,
	I am using SimplePDP to evaluate a request against a policy. I need
to include some homemade content in the ResourceContent section of the
request.xml, much like the resource-content example. Yet these homemade
content reside in our own namespace, so I need a way to insert the =
namespace
prefix declarations. Currently the encode function of RequestCtx only
outputs "<Request>" at the beginning. In the future it might be more
flexible to let the caller specify a namespace declaration (default to =
null)
before calling encode.

	Another issue I encountered is the classification of
general/target/condition functions in FunctionFactory. My specific =
problem
is to use a string-subset function as the MatchId for a SubjectMatch. =
Since
now subset function is called ConditionSetFunction, included as a member =
of
ConditionSetFunctionCluster, and initialized in initConditionFunctions =
in
StandardFunctionFactory, it means it can only be used in the Condition =
part
of a rule. Yet it looks that the code can also support using it in a =
target.
I am just curious about the rationale of this design and where the spec
requires so.

Thanks for any help.

Best Regards,
Jie Ren
