Overview

Priority 0.5: Namespace was hoisted on parent

When parent declared a namespace (as prefix OR default), children in that namespace MUST use the same format. If parent used default format (xmlns=“uri”), children inherit with NO prefix. If parent used prefix format (xmlns:p=“uri”), children use the same prefix.
