Subject: RE: DOCBOOK-APPS: Customization layer question for DocBook XML
What you want to do is turn off refentry.element before importing docbook, then you can safely redefine it afterwards. Something like this: > <!ENTITY % refentry.element "IGNORE"> > > <!--load DocBook--> > <!ENTITY % DocBookDTD PUBLIC "-//OASIS//DTD DocBook XML V4.2CR1//EN" > > "http://www.oasis-open.org/docbook/xml/4.2CR1/docbookx.dtd"> > %DocBookDTD; > > <!ELEMENT refentry %ho; (beginpage?, > (%ndxterm.class;)*, > refentryinfo?, refmeta?, > (remark|%link.char.class;)*, > refnamediv, (refsynopsisdiv?, > (refsect1+|refsection+)) > +) > %ubiq.inclusion;> Note that I also removed the <![%refentry.element;[ and <!--end of refentry.element-->]]> that wrapped your redeclaration (you do not want this turned off.
