Subject: Behavior of the to-lower-case function
Hi all, We from HERAS-AF implemented an XACML 2.0 evaluation
engine. Therefore we had to implement the function
The issue I am currently facing with this function
is that it does a “to lower case”. In XACML 2.0 it
simply says “This function SHALL take one argument of data-type ‘http://www.w3.org/2001/XMLSchema#string’
and SHALL normalize the value by converting each upper case character to its
lower case equivalent.”. No word about locales.
But to-lower-case always depends on the locale. In XACML 3.0 it says “Case mapping shall be done as specified for
the fn:lower-case function in [XF] with no tailoring for particular
languages or environments.”. I am not an expert in this area and don’t
really understand what is meant with “no tailoring for particular languages
and environments”. So my questions: ·
Should
the handling in XACML 2.0 be the same as in XACML 3.0? ·
How is
this meant “no tailoring for particular languages and environments”? I am looking forward to hearing from you. Regards Florian |
