Invoking Revocation

A revocation Action MUST take the following shape:

Field	Value
do	"ucan/revoke"
args	See [Arguments]
nonce	""

Note that per [UCAN Invocation], the nnc field SHOULD is set to "" since revocation is idempotent.

I'm a little confused by this section, and I wonder if there's just some outdated terminology that didn't get updated:

• "Action" is capitalized. Is it a term of art? I haven't found a definition for it. Is it (now) meant to be "Invocation"?
• Should do be cmd (as it would be if this is an Invocation)?
• Should nnc be nonce? (nnc is just the old name for this field, right?)
• Should the do/cmd be "/ucan/revoke", with a leading /?
