I am facing the same issue and I am unable to parse a valid wire file due to the absence of Addenda length in the tag {8200} Unstructured Addenda.

As per the below document faim 3.0.7 8200 tag modifications, the addenda length is no longer a valid field and the Addenda Information length has been updated to 9000 characters

https://www.frbservices.org/binaries/content/assets/crsocms/financial-services/wires/faim-3-0-7-tag-8200-changes-faq-july-2022.pdf

func (ua *UnstructuredAddenda) Validate() error {
	if err := ua.fieldInclusion(); err != nil {
		return err
	}
	if ua.tag != TagUnstructuredAddenda {
		return fieldError("tag", ErrValidTagForType, ua.tag)
	}
	if err := ua.isNumeric(ua.AddendaLength); err != nil {
		return fieldError("AddendaLength", err, ua.AddendaLength)
	}
	if err := ua.isAlphanumeric(ua.Addenda); err != nil {
		return fieldError("Addenda", err, ua.Addenda)
	}

	return nil
}

As per the logic, we still validating the addenda length.

Can confirm, we started receiving wires with the new tag 8200 format which is:

1. a multi-line XML
2. without the addenda length part.

e.g. something like

{8200}<!--<Document xmlns="urn:iso:std:iso:20022:tech:xsd:pacs.008.001.08">
