!!! Overview
[{$pagename}] ([vtr]) defined in [Vectors of Trust] and used in [OpenID Connect], the client MAY request a partial set of acceptable VoT values with the "vtr" (vector of trust request) claim  request as part of the Request Object.  

The value of this field is a [JSONArray] of [strings] [RFC 8259], each string identifying an acceptable set of vector components.  The component values within each vector are ANDed together while the separate vectors are ORed together.  For example, a list of vectors in the form:\\
'"P1.Cb.Cc.Ab", "Ce.Ab"' is stating that either the full set of "P1 AND Cb AND Cc AND Ab" simultaneously OR the full set of "Ce AND Ab" simultaneously are acceptable to this [Relying Party] for this [transaction].

[{$pagename}] values [MAY] omit components, indicating that any value is acceptable for that component category, including omission of that component in the response vector.

The mechanism by which the [IDP] processes the "[vtr]" and maps that to the [authentication] transaction are out of scope of this specification.
