Hi All,

I came across a case where the following error is reported only when iXBRL is validated via command line and not via GUI

[xmlSchema:valueError] Element attribute substitutionGroup value error: xbrldt:hypercubeItem, Namespace is not defined by an import or include element 

(The import for "http://www.xbrl.org/2005/xbrldt-2005.xsd" was missing in the file.) The iXBRL was accepted by SEC as well.

Following is the validation command I am using : 
arelleCmdLine.exe -f "{filepath}" --disclosureSystem="efm-pragmatic" --validate --plugins="xule|validate/DQC|EDGAR/transform|validate/EFM" -v --noCertificateCheck  --calcDecimals --calcPrecision --calcDeduplicate

So my question is which result is valid ? Or is validation from GUI missing something ?

Hi Devayani,

I can take a look. Can you provide a link to the SEC filing?

Thanks,

Hi Devayani,

To load the filing you need to enable the inlineXbrlDocumentSet plugin. In the GUI you likely have that enabled already, but not in your CLI commend.

Kind regards,
