XACML Committee Specification 1.0 (Revision 1), 12 December 2002
Title: Errata List
Version: 1.2, 03/01/09 (yymmdd)

Errata are in order according to location in the document.  Each
erratum has a STATUS indicating whether it has been approved by

2.1 Requirements, pdf:357-358

When I read the line #[357-358], I got the impression that this
is about creating policy sets, but this is about combining rules
and policies to evaluate authZ decision. I think changing the
term "action" to "access request" makes it clear. At the same
time, the objective of combining rules and policies is to
evaluate the consolidated authorization decision and not to
create a policy set(?). I would say statement like "To provide a
method for combining individual rules and policies to evaluate
authZ decision that applies to a given access request" is more
clear. Lines #[403-405 2.3 Combining algorithms] indicate the

STATUS: Not erratum.  Leave as is.  The word "action" has already
been changed to "decision request", and that is bolded to
indicate it is defined in the glossary.
A.2 Primitive types

Add something to mention the extensibility of the data type

leave doc as is.
A.3 Structured types, pdf:3408

1) Replace "xsi:string" by the correct URI.
2) Replace "XMLSchema-Instance#string" by "XMLSchema#string"

A.6 Expressions, pdf:3458-3461

Section A.6 states that all expressions listed below evaluate to either a
primitive type, or a bag of primitive types.

This needs to be enhanced because of the <Function> argument, and also it
states nothing of extension types.

I suggest the following wording:

Change the first paragraph to:

XACML specifies expressions in terms of the following elements of which
the <Apply> and <Condition> elements recursively compose greater
expressions.  Valid expressions shall be type correct, which means that
the types of each of the elements contained within <Apply> and <Condition>
elements shall agree with the respective argument types of the function
that is named by the FunctionId attribute.  The resultant type of the
<Apply> or <Condition> element shall be the resultant type of the
function, which may be narrowed to a primitive data type or a bag of a
primitive data type by type unification. XACML defines an evaluation
result of "Indeterminate", which is said to be the result of an invalid
expression, or an operational error occurring during the evaluation of the

STATUS: Polar requested to supply clarification of "type
unification", which is not defined anywhere in the spec.
