XML namespace
DocBook 5
The semantic vocabulary for DocBook 5 books, articles, sections, procedures, references, and technical inline markup.
xmlns="http://docbook.org/ns/docbook"DocBook 5 places its complete vocabulary in this namespace, normally declared as the default on <book> or <article>. The move to a namespace is the clearest structural distinction from namespace-free DocBook 4 documents.
Publishing pipelines transform these semantic elements into presentation formats. Extensions such as XLink may add their own namespace attributes without changing the DocBook identity of the containing elements.
