@geostonemarten Apparently, the constraint comes from ElementTree, the Python XML library. From what I can read in the source code, any namespace that is named ns followed by a number is reserved.

[geostonemarten]

Ok this is a language limite. Can you overload namespace if ns* is detected in the source file?

@geostonemarten did you mean deleted rather than detected ?

I was getting the error with a file with the following prefixes:
