But in the previous scenario, this was not necessary - the custom data
schemas could simply be parsed out of the input.
So is this is a change which needs to be noted in the APPEL spec?
Also - here is another question. When it comes to "category expansion"
(APPEL spec 5.4.6) , is it possible that the data-group element in the APPEL
ruleset could refer to an inline or external schema which would then be
needed to expand the category?
Or are you saying that
a. APPEL rulesets never include any of the data schemas they refer to
b. Category expansion can only ever take place over the p3p base data
