vp_formats_supported definition issue #681
Description
The definition for vp_formats_supported in section 11.1 is somewhat confusing, the current text is
REQUIRED. An object containing a list of name/value pairs, where the name is a Credential Format Identifier and the value defines format-specific parameters that a Verifier supports. For specific values that can be used, see Appendix B. Deployments can extend the formats supported, provided Issuers, Holders and Verifiers all understand the new format.
Namely "An object containing a list of name/value pairs" which could be updated to "An object containing name/value pairs". This avoids any confusion with the term "list" thats often used to describe a JSON array.
