Overview

Special namespace class representing the blank namespace (xmlns=“”)

Used when elements explicitly need to opt out of their parent’s default namespace per W3C XML namespace semantics.

When a parent element uses default namespace format (xmlns=“uri”) and a child element should be in the blank namespace, the child must explicitly declare xmlns=“” to prevent inheriting the parent’s default namespace.

Examples:

Parent with default namespace, child needs blank

<root xmlns="http://example.com/ns">
  <child xmlns="">Value</child>
</root>
