Apache Daffodil default triad separator clashes with the comma as EDIFACT decimal separator

[uliSchuster]

Apache Daffodil uses both a decimal separator (textStandardDecimalSeparator) and a thousand group separator (textStandardGroupingSeparator). The group separator by default is the comma. Setting the decimal separator to be the comma as well leads to a clash. This situation arises during EDIFACT parsing either if the comma is set in the service string advise – i.e., UNA:+,? ' – or when setting the comma as default decimal separator when configuring smooks – e.g.,

val reader = EdifactReaderConfigurator(schemaUri)
reader.setDecimalSign(",")
smooks.setReaderConfig(reader)

The resulting error is

org.smooks.api.SmooksException: Failed to filter source
[..]
Caused by: org.smooks.api.SmooksException: Schema Definition Error: Non-distinct property ',' found in: textStandardGroupingSeparator, textStandardDecimalSeparator
Schema context: E0017 Location line 3334 column 14 in jar:file:.m2/repository/org/smooks/cartridges/edi/edi-schemas/2.0.0-RC1/edi-schemas-2.0.0-RC1.jar!/EDIFACT-Common/EDIFACT-Service-Segments-4.1.dfdl.xsd

A workaround is to set the Daffodil triad separator to some character that is not used in EDIFACT, like reader.setDecimalSign(",").setTriadSeparator("~"). However, it would be great if the smooks EDIFACT cartridge would take care of this issue in its default configuration
