Invoice xmlns prefix

[alkahtani]

I have followed the CreateInvoiceFromScratch and the invoice successfully created in the Target folder but i have an issue with the prefix of CommonExtensionComponents namespace xmlns:cec="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2 , is it possible to have it "ext" like xmlns:ext="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2 as it is important for me to do validation and integration with existing systems

Please help.

Thank you
