I'm starting a new documentation project and considering DocBook. What are the key differences between DocBook V5.x and V4.x, specifically regarding their schema languages and namespace usage? Which version is recommended for new projects, and where can I find their specifications?
Navigate to 'docbook.org'. Click on the 'Schemas' link. Identify the schema languages available for DocBook V5.x and V4.x. Note the information regarding namespaces for DocBook V5.x. Determine which version is the focus of current development. Click on the 'Specifications' link to find the online specifications. Synthesize the differences between V5.x and V4.x, the recommended version for new projects, and where to find their specifications.
The agent successfully navigates to the 'Schemas' page. The agent identifies that DocBook V5.x schemas are available in RELAX NG, W3C XML Schemas, and XML DTDs. The agent identifies that DocBook V4.x is DTD-based. The agent states that DocBook V5.0 and later are in a namespace, specifically 'http://docbook.org/ns/docbook', while V4.x is not. The agent states that V5.x schemas are the focus of current development and are recommended for new projects. The agent provides the link to the online specifications for current and historical releases.
