Removes the specified namespace from a collection.
objXMLDOMSchemaCol.remove(namespaceURI)
HRESULT remove(BSTR namespaceURI);
This may be any string that can be used in an xmlns attribute, but it cannot contain entity references. The same white space normalization that occurs on the xmlns attribute occurs on this argument (that is, leading and trailing white space is trimmed, new lines are converted to spaces, and multiple adjacent white space characters are collapsed into one space).
