xmlns value in xmlport

mmostacchi

Hi all
I have an attribute in xmlport called "xmlns"
When I run the export in the file I find this value: xmlns = ""

I need this value:
xmlns = "http://www.fatturapa.gov.it/sdi/fatturapa/v1.0"

I tried to write this code inside "xml - Export::onbeforepassvariable()":
"xmlns" := 'http://www.fatturapa.gov.it/sdi/fatturapa/v1.0'
But the export doesn't run...

Any idea?
