New issue 1780: [ed] Clean up and align terminology sections across three OpenID4VC specs
https://bitbucket.org/openid/connect/issues/1780/ed-clean-up-and-align-terminology-sections

Kristina Yasuda:

* definitions of the same terms are not consistent across three OpenID4VC specs
* would improve readability if the order of the same terms is consistent across three OpenID4VC specs
