No, I didn't say that. DocBook 4.3 is upwardly compatible with DocBook 4.2. Any DocBook 4.2 is also a DocBook 4.3 document (the opposite being not necessarily true). [1] If you have modified the system-wide XML catalog to make "-//OASIS//DTD DocBook XML V4.2//EN" to the DocBook 4.3 DTD, then your ``strange indention'' problem is solved: XXE works as expected. DocBook 4.2 <caption> may not contain #PCDATA: --- <caption> <para>Component view of the Sectra Cardiology Package and its interaction with IDS5</para> </caption> --- DocBook 4.3+ <caption> may contain #PCDATA: --- <caption><para>Component view of the Sectra Cardiology Package and its interaction with IDS5</para></caption> --- [2] If you intend to upgrade from a DocBook version to newer ones, it is annoying to add --- <!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN" "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd";> --- at the top of your documents, simply because sooner or later this information will become incorrect. I would recommend: * Not to add a <!DOCTYPE> to your documents (or a <!DOCTYPE> with just character entities). This is the implicit grammar approach: the way of the future IMHO. See DSDL/NRL -- http://www.idealliance.org/papers/dx_xml03/papers/04-05-03/04-05-03.html * OR add something like this: --- <!DOCTYPE book SYSTEM "http://www.sectra.se/dtd/docbook/current/docbookx.dtd";> --- and change XXE configuration and system-wide XML catalog accordingly. * OR never upgrade your documents to newer DocBook DTDs (by far, my favorite one!).
