-For example, if the data Carol and Oscar saw in the resume was

+### Minimal Credential Disclosure ### {#uc-minimalcredentials}
+
+Following a link on a blog post, Alice comes to a resource that requires
+authentication. She could present one of many verifiable credentials (as per 
+[[#capabilities-vc]]): three self-signed WebID credentials, four bank accounts,
+a drivers licence, two passports, a proof that she is over 18, a credential
+for her college and her university diploma, three club memberships as well
+as her FBI credential.  The resource only requires proof of being over 18.
+Her client's credential manager should see this and select 
+the credential revealing the least amount of information needed to access 
+the resource.
