Seems, I don't get the differenence at the moment.
Comparing
<DATA-STRUCT name="vehicle.built.where"
structref="http://www.w3.org/TR/P3P/base#postal">
<CATEGORIES><preference/></CATEGORIES>
</DATA-STRUCT>
to
<DATA-DEF name="dynamic.clickstream"
structref="#loginfo">
<CATEGORIES><navigation/><computer/></CATEGORIES>
</DATA-DEF>
, the only difference I see is the use of DATA-STRUCT vs.
DATA-DEF. Do you mean, that using a DATA-STRUCT
tag *overrides* the categories inherited (inherited because
of the structref attribute), whearest using
a DATA-DEF tag does not?
If there is no such difference,
"dynamic.clickstream.ANYTHING" should be in the
<navigation/> and <computer/> categories
(as in the example above).
Best,
Nikolaj
