e.input.format.contact.¶

e.input.format.contact. is a match pattern, never a code. It selects every code below it, including ones minted after your handler was written.

Codes under this prefix¶

• e.input.format.contact.aid.f — That isn't a well-formed identifier, so there is nothing for me to write down.
• e.input.format.contact.trans.f — That identifier can rotate its keys, so the identifier alone tells me nothing about it.
