<!-- Ruby Common Attributes

     The following optional ATTLIST declarations provide an easy way
     to define common attributes for ruby elements.  These declarations
     are ignored by default.

     Ruby elements are intended to have common attributes of its
     parent markup language.  For example, if a markup language defines
     common attributes as a parameter entity %attrs;, you may add
     those attributes by just declaring the following parameter entities

         <!ENTITY % Ruby.common.attlists  "INCLUDE" >
         <!ENTITY % Ruby.common.attrib  "%attrs;" >

     before including the Ruby module.
