OptionalfieldsFields to place for this signer (signature, date, initials, …) and WHERE to place them. When omitted or empty, the driver emits no explicit placement and the provider applies its own default — see SignatureFieldPlacement. Prefer anchor-string placement; fall back to normalized coordinates only when the document has no usable marker.
OptionalnameOptionalroleTemplate role name, when using BaseSignatureProvider.ApplyTemplate.
OptionalroutingSigning order; lower routes first. Defaults to 1 per recipient if omitted.
A signer to be added to an envelope.
