The end-2-end identifier, as intended by ISO20022, is the
same concept of the cbc:InvoicingPartyReference we currently have in the UBL
RemittanceAdvice document.
The definition is strictly that one provided by UBL 2.0, "The Invoicing
Party's reference to the payment, previously requested of the Payer to
accompany remittance."
Into UBL this is a textual reference and not an identifier, but the bigger
problem is to clarify the relationship between this reconciliation reference
information and the Invoice line items.
I think there is not a precise rule for this, as it is up to the Invoicing
Party to indicate one or more references for reconciliation purposes.
Such reference could be associated to a single invoice line item, a set of
line items, a complete invoice, more than one invoice and even different
parts of different invoices.
The solution seems to be to provide this InvoicingPartyReference at line Item
and in the root of the document (RemittanceAdvice and Invoices)

To be evaluated by Tim McGrath as this is a cross-domain
information transported end-2-end for reconciliation purposes. Also it
impacts on many UBL documents (Invoice, RemittanceAdvice, ...)
