Openser does not implicitly check an option-tag.
If you need such a check, you have to do it manually, reading the Require: header and check it against a local list of supported options.
IMHO the registrar (which acts as a UAS) should inspect the Require tags by itself.
Same as when the presence server inspects the Event header based on the loaded modules (dialog, presence, mwi...).
