[ACTION-121] Jirka to summarize usage of Ruby in DocBook

Hi,

the standard part of DocBook distribution is ITS augmented schema which
contains additional elements for Ruby in ITS namespace. Schema is
available at http://www.docbook.org/xml/5.0/rng/dbits.rnc

So today, you can use Ruby inside DocBook in the following way:

<book
  xmlns="http://docbook.org/ns/docbook";
  xmlns:its="http://www.w3.org/2005/11/its";
  version="5.0">
 <title>...</title>
 <chapter>
  <title>...</title>
  <para>この本は <its:ruby>
    <its:rb>慶応義塾大学</its:rb>
    <its:rp>(</its:rp>
    <its:rt>けいおうぎじゅくだいがく</its:rt>
    <its:rp>)</its:rp>
   </its:ruby>の歴史を説明するものです。</para>
 </chapter>
</book>

However usage is probably very small because standard stylesheets are
not supporting Ruby yet and there were only spare request for this.

Based on this I assume that DocBook can live with simplified Ruby model
in ITS 2.0 based on one from HTML5.
