I18N Review: does Policy Metadata need Unicode normalization

Hello POE WG,

The I18N WG reviewed your drafts odrl-model and odrl-vocab (thanks for
the self-review!) and found no i18n issues, except for this question:

In the section Policy Metadata[1], there are strings that may be added
to a Policy, in particular Dublin Core metadata. These strings are in
Unicode, but the specification doesn't say if they are normalized.

That is not necessarily a problem, unless those strings are compared to
other strings (to build conditions, for search, etc.). It seems indeed
these strings aren't used by ODRL in any comparisons. Is that the case?

Thanks for the feedback @bert-github

We discussed this at the WG teleconference yesterday [1] and we agreed that the dublin core metadata properties used in an ODRL Policy are not designed to be used for comparisons.

We will add a note to that effect in that section to be clear.
