[xacml] is-present-designators

[simon godik <simon@godik.com>]

There is a way to test if attribute is present without using is-present-designator elements:

It is to compare bag size selected by the designator to 0:

 

<apply function-id="integer-greater-than">

    <apply function-id="type-bag-size">

        <attribute-designator ..../>

    </apply>

    <attr-val ...>0</attr-val>
</apply>

 

My proposal is to drop is-present-attribute-designators
