The use of SpecifiedTradeSettlementPaymentMeans several times

[simon-gotomaxx]

According to the documentation, SpecifiedTradeSettlementPaymentMeans can be used multiple times to specify multiple banks. If I do this, I get an error message when validating:

<error type="18">schema validation fails:org.xml.sax.SAXParseException; lineNumber: 273; columnNumber: 46; cvc-complex-type.2.4.a: Ungültiger Content wurde beginnend mit Element '{"urn:un:unece:uncefact:data:standard:ReusableAggregateBusinessInformationEntity:100":SpecifiedTradeSettlementPaymentMeans}' gefunden. '{"urn:un:unece:uncefact:data:standard:ReusableAggregateBusinessInformationEntity:100":ApplicableTradeTax}' wird erwartet.</error> <error type="4" location="/*[local-name()='CrossIndustryInvoice']/*[local-name()='SupplyChainTradeTransaction']/*[local-name()='ApplicableHeaderTradeSettlement']" criterion="count(ram:SpecifiedTradeSettlementPaymentMeans)&lt;=1">Element 'ram:SpecifiedTradeSettlementPaymentMeans' may occur at maximum 1 times. from /xslt/ZF_221/FACTUR-X_EN16931.xslt)</error>

When I check the same XML via the KoSIT Valitator, there are no problems.

Here is an excerpt of the corresponding passage from the XML:

If your issue is a question if a mustang generated file is valid(?) please include either the complete source code and/or the complete output so that I can have a look and run it through a validator

[simon-gotomaxx]

I create the ZUGFeRD file in a custom application (Mustang is not used). I use Mustang (Mustang-CLI-2.11.0.jar) for validation and am wondering about the error message.
Attached is the XML that produces the above error during validation.
factur-x.zip

The error only occurs when I use SpecifiedTradeSettlementPaymentMeans multiple times. This should be possible according to the general ZUGFeRD documentation.

[IsThatUniqueEnough]

In the FACTUR-X schemas below the EXTENDED profile the cardinality of SpecifiedTradeSettlementPaymentMeans is [0..1].

[simon-gotomaxx]

Ah ok now I see it.
<assert test=‘count(ram:SpecifiedTradeSettlementPaymentMeans)<=1’>
Element ‘ram:SpecifiedTradeSettlementPaymentMeans’ may occur a maximum of 1 time.</assert
(from the FACTUR-X_EN16931.sch schematron)

It is just a bit confusing as it is described in the documentation and even more so if it is allowed in xRechnung (EN16931).
