Is it possible to send attachments through CMK AR Invoices (UBL-2.1-PEPPOL-Invoice-Out)

Summary:

We are implementing PEPPOL for AR Invoices outbound using the standard message available in UBL-2.1-PEPPOL-Invoice-Out. There is no documentation that mentions about sending invoice attachments in the XML file. We would like to know if we can send invoice attachments through CMK AR ?
