Add a custom namespace and use it in openxml excel via c# openxml sdk

Question

Is there an example to add a custom namespace

e.g.

xmlns:bluh = "http://www.bluhbluh.com"

at Workbook/WorkbookPart/SpreadSheetDocument level

using a C# OpenXml SDK?

You can't add a custom namespace to the spreadsheet, word document, etc... OOXML format doesn't allow it.
