[Bug]: [W1][xmlport][37200][Sales Cr.Memo - PEPPOL30] is not valid by XSD scheme

Describe the issue

XMLport for exporting credit memos to the Peppol BIS3 XML format was probably created as a copy of the invoice export, because it has the same structure of elements. But the XML file generated by this XMLport is not valid against Peppol UBL CreditNote scheme.

The XML element TaxPointDate is misplaced and should be moved rigth after the IssueDate element.

In the standard implementation of the providers, TaxPointDate value is empty and therefore it is not exported to the XML file and, therefore, the XML file without TaxPointDate is valid. But when the implementation of interface "PEPPOL Document Info Provider" is overridden and TaxPointDate has a value, the validation fails.

Expected behavior

The XML element TaxPointDate should be placed according to the XSD scheme, or as there is a definition on https://docs.peppol.eu/poacc/billing/3.0/syntax/ubl-creditnote/tree/.

Steps to reproduce

A new implementation of the interface is needed and there should be variable TaxPointDate filled.

Start by locating the PEPPOL BIS3 XMLport that exports credit memos and inspect the element order around IssueDate and TaxPointDate. Move TaxPointDate to the position required by the UBL CreditNote XSD, then validate an export with a populated TaxPointDate against the Peppol scheme.
