Make doctype_value and vct_values mandatory

[martijnharing]

closes #413

[danielfett]

if we merge #479, the new parameter types_values for W3C VCs needs to be updated to be MANDATORY as well.

[danielfett]

@martijnharing please make the new type_values for W3C credentials mandatory as well and @c2bo can probably tell us which of schema_id_values and cred_def_id_values we should make mandatory as well

I'd say at least one of schema_id_values or cred_def_id_values MUST be present. In theory it would be schema ID and did or cred_def_id as far as I understand the current AnonCreds iteration @TimoGlastra?

[TimoGlastra]

Yes we basically use did + schema id to query, as this doesn't limit key rotation through the credential definition.

I think that at least one of them needs to be defined makes sense. Not sure if it's an AND or an OR, but it's never really needed to include both.

[danielfett]

In that case, requiring one of them to be present seems reasonable. @martijnharing

WG discussion
for AnonCreds, one of the schema_id_values or cred_def_id_values must be present.
for W3C, type_values must be present
