Why Protege add the `xml` namespace to my ontology?

I'm using Protégé to edit my ontology, but everytime it adds xml namespace to it.

xml http://www.w3.org/XML/1998/namespace

I don't know why, and I didn't use it anywhere in my ontology.

enter image description here

And the delete option is always disabled for xml.

The XML prefix is part of the prefixes that are always written out - owl, rdf, rdfs, xsd, xml. There is no logical implication, these are plain shortcuts used in the XML layer; if unused, their effect is nil. If used, they reduce the size of the output file.
