Scheme and List attributes present causes Warnings

[DemigodCode]

Is there any reason why those attributes are at e.g. TaxCategory ID?

All Validators are warning that that should not be present.

I can't upload the file to two Peppol Access Points.

Hey @DemigodCode

Are you talking about this in TaxCategory?

ubl-invoice/src/TaxCategory.php

Lines 47 to 54 in 3ee8087

	public function setId(?string $id, $attributes = null): TaxCategory
	{
	$this->id = $id;
	if (isset($attributes)) {
	$this->idAttributes = $attributes;
	}
	return $this;
	}

If so, at least I, do not see any references in the documentation that these attributes should be set.
But for now, you can pass an empty array for the $attribute parameter when setting id as a workaround:

$taxCategory = (new TaxCategory)
            ->setId(UNCL5305::STANDARD_RATE, [])

Hello,

@DemigodCode , are you talking about the warning UBL-CR-678 ("A UBL invoice should not include the TaxCategory/ID schemeID")?
I use this document as reference: https://docs.peppol.eu/poacc/billing/3.0/2023-Q4/bis/ , you can search "UBL-CR-678".
I use this validator to validate my XML's: https://www.ubl.be/validator/ .

If yes, to solve this warning, I update the class NumNum\UBL\TaxScheme::xmlSerialize():
