(Probably, the discussion I proposed in this post seems too scholastic, but it is still close related to DocBook tools and, as I hope, will be able to discover some serious problems.)
1. DocBook XML V5.0 was released two and a half years ago. "Schemas for DocBook 5.0 are available in several formats, but only RELAX > NG schema is normative and thus preferred. Other schemas are not fully > RELAX NG compatible and provided as a convenience for using with legacy > tools." [Norman Walsh, DocBook 5: The Definitive Guide] 2. DocBook XSLT Stylesheets 1.77.0 was released two weeks ago. Download statistics (http://sourceforge.net/projects/docbook/files/): ================ docbook-xsl-ns (RELAX NG) - 30 696 downloads (8.5%) docbook-xsl (DTD) - 329 401 downloads (91.5%) ------------------------------------------------------------------------------------ Total: - 360 097 downloads (100%) Only 8.5% of users have transited to RELAX NG, the rest are still stuck to "old-fashioned" DTD. Not too brilliant result for 2.5 years, is it? Why? *What prevents transition to the new functionality of DocBook 5?* Any idea? -- Regards, Ivan Zaporozhets Divine Dandelion℠ Online Publishing Service http://divinedandelion.blogspot.com/
