Research direction

Start by reproducing the delay with a UBL invoice containing the unknown unit code and the undeclared http://www.w3.org/2000/09/xmldsig#:Signature element, then compare it with a CII invoice. Review issue #221 for the related prior fix. Done means UBL invoices open promptly and the reported document is interpreted correctly.

Description

Hi Chris,

I'm using version 2.9.0.7 now, installed today. Most invoices are in CII format, but all those in UBL take minutes to open. Of course XML files (especially electronic invoices) are meant to be processed by computers and not by humans, but in this case it is not interpreted correctly, and I have to check why (here, it was an unknown-to-us unit code).

Something similar you already solved in issue #221 in September 2022. And it again starts with http://www.w3.org/2000/09/xmldsig#:Signature-Element being not declared. I'm using this on a Windows Server 2019 with a freshly installed Dotnet 4.8 library, which was a hassle to install (and update).

I'll send you the document on request, as I did then :)

Kind regards,
Werner
