Problem with Schema file, UBL Invoice 2.1

[Slavica ÄakoviÄ <sladja987@gmail.com>]

Hello,

I don't know why it is impossible to get the correct (valid) Schema file (xsd file) from this ubl e-invoice 2.1 xml file, or from original xsd fileÂ

https://docs.oasis-open.org/ubl/os-UBL-2.1/xsd/maindoc/UBL-Invoice-2.1.xsd

I try to do it through different programs, but the resulting xsd always has an error.

For example, this is an error which is popping up on the screen for the file that is obtained when .xsd is generated from valid xml file, through the "xsd.exe" program:

The "urn:oasis:specification:ubl:schema:xsd:CommonExtensionComponents-2:Party'element is not declared'

OR

https://www.utilities-online.info/xsdvalidation

When I do validation xml and xsd file they both Ok. But when I try validate xml againstÂxsd I got the error:
